:speedboat: Quickstarts

Get started with our quickstart recipes.

🏁 Getting Started

Installation

You don't need this source code unless you want to modify it. If you want to use the package, just run:

pip install apiaudio -U
#or
pip3 install apiaudio -U

Install from source with:

python setup.py install
#or
python3 setup.py install

Prerequisites

Python 3.6+

🚀 Hello World

Create a file hello.py

touch hello.py

Authentication

This library needs to be configured with your account's api-key which is available in your api.audio Console. Import the apiaudio package and set apiaudio.api_key with the api-key you got from the console:

import apiaudio
apiaudio.api_key = "your-key"

Create Text to audio in 4 steps

Let's create our first audio asset.

✍️ Create a new script, our scriptText will be the text that is later synthesized.

script = apiaudio.Script.create(scriptText="Hello world")
print(script)

🎤 Render the scriptText that was created in the previous step. Lets use voice Aria.

response = apiaudio.Speech.create(scriptId=script["scriptId"], voice="Aria")
print(response)

🎧 Now let's join the speech we just created with a sound template.

response = apiaudio.Mastering.create(
    scriptId=script.get("scriptId"),
    soundTemplate="jakarta"
    )
print(response)

Download the final audio asset to your current working directory:

filepath = apiaudio.Mastering.download(scriptId=script["scriptId"], destination=".")
print(filepath)

Easy right? 🔮 This is the final hello.py file.

import apiaudio
apiaudio.api_key = "your-key"

# script creation
script = apiaudio.Script.create(scriptText="Hello world")

# speech creation
response = apiaudio.Speech.create(scriptId=script["scriptId"], voice="Aria")

print(response)

# mastering process
response = apiaudio.Mastering.create(
    scriptId=script.get("scriptId"),
    soundTemplate="jakarta"
    )
print(response)

# download
filepath = apiaudio.Mastering.download(scriptId=script["scriptId"], destination=".")
print(filepath)

Now let's run the code:

python hello.py
#or
python3 hello.py

Once this has completed, find the downloaded audio asset and play it! :sound: :sound: :sound:

📑 Documentation

Import

import apiaudio

Authentication

The library needs to be configured with your account's secret key which is available in your Aflorithmic Dashboard. Set apiaudio.api_key with the api-key you got from the dashboard:

apiaudio.api_key = "your-key"

Authentication with environment variable (recommended)

You can also authenticate using apiaudio_key environment variable and the apiaudio SDK will automatically use it. To setup, open the terminal and type:

export apiaudio_key=<your-key>

If you provide both an environment variable and apiaudio.api_key authentication value, the apiaudio.api_key value will be used instead.

Super Organizations

In order to control a child organization of yours, please use the following method to assume that organization id.

Set your child organization id to None to stop assuming an organization. Subsequent calls to the api will use your own organization id.

import apiaudio

apiaudio.set_assume_org_id('child_org_id')

# Stop using
apiaudio.set_assume_org_id(None)

See organization resource for more operations you can perform about your organization.

Resource Usage

There are two approaches to use the resources.

The recommended approach is to import all resources directly from apiaudio:

import apiaudio
apiaudio.Script.create()

Alternatively, you can import the resource classes you want to use first, and then use the resource methods. For example, to use Script, we could do:

from apiaudio import Script
Script.create()

Same logic applies for other resources (Speech, Voice, Sound...)

Organization resource

The Organization resource/class allows you to perform some data retrieval about your organization and your child organizations.

Organization methods are:

• get_org_data() - Get organizations data, including orgId, orgName etc.
  • Parameters:
  • None.
  • Example:

    org_data = apiaudio.Organization.get_org_data()

• list_child_orgs() - List your child organizations.
  • Parameters:
  • None.
  • Example:

    child_orgs = apiaudio.Organization.list_child_orgs()

• get_secrets() - Get your api key, webhook url and webhook secret.
  • Parameters:
  • None.
  • Example:

    secrets = apiaudio.Organization.get_secrets()

Script resource

The Script resource/class allows you to create, retrieve and list scripts. Learn more about scripts here.

  • public (boolean): If True, the media files listed will be the public media files provided by api.audio. Default is False.

  • Examples:

  # lists all files
  files = apiaudio.Media.list()
  
  # lists files with tag="tag1"
  files = apiaudio.Media.list(tags="tag1")
  
  # lists file with specific id
  files = apiaudio.Media.list(mediaId="some_mediaId")
  
  # lists files with tag="tag1" and with a downloadurl
  files = apiaudio.Media.list(tags="tag1", downloadUrl=True)

• list_tags() This returns a list with all unique user defined tags.

  • Parameters:
  • No parameters required.

• Example:

  tags = apiaudio.Media.list_tags()
  print(tags)

• get_download_url() - This method returns a presigned url for downloading a specific audio file

  • params:
  • mediaId * [required] (string): media id for the file to be downloaded

• Example

  url = apiaudio.Media.get_download_url(mediaId="some-mediaId")
  print(url)

SyncTTS resource

SyncTTS allows you to do Synchronous Text-To-Speech (TTS) with our API using all the voices available. Use it to create a speech audio file from a text and a voice name. The response contains wave bytes ready to be played or written to a file.

SyncTTS methods are:

• create() Create a TTS speech file.

  • Parameters:

  • voice * [Required] (string) - The voice name. See the list of available voices using Voice resource.

  • text * [Required] (string) - The text you want to do TTS with. The limit is 800 characters for wave files.

  • metadata [Optional] ("full" or "none") - The level of metadata you want. Returns phoneme lists (only available for some msnr voices)

  • Example:

    sync_tts = apiaudio.SyncTTS.create(
    voice="joanna",
    text="This is me creating synchronous text to speech",
    metadata="full"
    )

Birdcache resource

Birdcache is a caching service provided by API.audio that provides the caching layer for the customer by storing data in API.audio servers for future use. This allows you to retrieve your speech files on the fly.

Birdcache methods are:

• create() Create a TTS speech file.

  • Parameters:

  • type * [Required] (string) - Type of the event. Supported types are mastering and speech.

  • text * [Required] (string) - The text you want to do speech/mastering with. See the example for personalisation parameters.

  • voice * [Required] (string) - The voice for speech creation.

  • audience * [Optional] (dict) - The key pair object for personalisation parameters. See the example below.

  • soundTemplate [Optional] (string) - The sound template for mastering creation. Only needed when the type is mastering.

  • Example:

    birdcache = apiaudio.Birdcache.create(
    type="mastering",
    voice="linda",
    text="This is {{username|me}} creating synchronous text to speech",
    audience={"username": ["salih", "sam", "timo"]},
    soundTemplate="electronic"
    )

Pronunciation Dictionary resource

Often when working with TTS, the models can fail to accurately pronounce specific words, for example brands, names and locations are commonly mis-pronounced. As a first attempt to fix this we have introduced our lexi flag, which works in a similar way to SSML. For example, adding <!peadar> instead of Peadar (who is one of our founders) to your script will cause the model to produce an alternative pronunciation of this name. This is particularly useful in cases where words can have multiple pronunciations, for example the cities ‘reading’ and ‘nice’. In this instance placing <!reading> and <!nice> will ensure that these are pronounced correctly, given the script:

" The city of <!nice> is a really nice place in the south of france."

If this solution does not work for you, you can instead make use of our custom (self-serve) lexi feature.

This can be used to achieve one of two things, correcting single words, or expanding acronyms. For example, you can replace all occurrences of the word Aflorithmic with “af low rhythmic” or occurrences of the word ‘BMW’ with “Bayerische Motoren Werke”. Replacement words can be supplied as plain text or an IPA phonemisation.

Prononciation dictionary methods are:

• list() Lists the publicly available dictionaries and their words

  • Parameters:

  • none

  • Example:

  # returns a list of public dictionaries
  dictionaries = apiaudio.Lexi.list()
  

• list_custom_dicts() Lists the custom dictionaries and their respective words

  • Parameters:
  • none
  • Example:

  # returns a list of custom dictionaries
  types = apiaudio.Lexi.list_custom_dicts()
  

• register_custom_word Adds a new word to a custom dictionary.

  • lang [required] (string) - Language family, e.g. en or es.dictionary - use global to register a word globally.
  • word [required] (string) - The word that will be replaced
  • replacement [required] (string) - The replacement token. Can be either a plain string or a IPA token.
  • contentType [optional] (string) - The content type of the supplied replacement, can be either basic (default) or ipa for phonetic replacements.
  • specialization [optional] (string) - by default the supplied replacement will apply regardless of the supplied voice, language code or provider. However edge cases can be supplied, these can be either a valid; provider name, language code (i.e. en-gb) or voice name.
  • Example:

    # correct the word sapiens
    r = apiaudio.Lexi.register_custom_word(word="sapiens", replacement="saypeeoons", lang="en")
    print(r)

  For each language, only a single word entry is permitted. However, each word can have multiple specializations. When a word is first registered a default specialization is always created, which will match what is passed in. Subsequent calls with different specializations will only update the given specialization. The exact repacement that will be used is determined by the following order of preference:

  voice name > language dialect > provider name > default

  For example, a replacement specified for voice name sara will be picked over a replacement specified for provider azure.

• list_custom_words() Lists all the words contained in a custom dictionary.

  • Parameters:

  • lang [required] (string) - Language family, e.g. en or es - use global to list language agnostic words.

  • Example:

    # lists all words in the dictionary along with their replacements
    words = apiaudio.Lexi.list_custom_words(lang="en")

Preview

The effect of applying the Pronunciation Dictionary can be seen with the script.preview() method. See Script documentation for more details.

• Example:

  text = """
    The author of this repo has lived in two places in the
    UK, <!Bude> and <!Bristol>
  """
  
  r = apiaudio.Script.create(scriptText=text)
  scriptId = r["scriptId"]
  
  # preview the script in en-gb
  preview = apiaudio.Script.preview(scriptId=scriptId, voice="Joanna")
  print(preview)

• Response:

  {"preview" : "The author of this repo has lived in two places in the UK, bude and <phoneme alphabet=\"ipa\" ph=\"###\"> bristol </phoneme>"}

  In this example Bristol will be phonemised to ensure it is correctly pronouced, but as Bude is not in our a dictionaires it is left as is. The exact IPA tokens for words in our internal dictionaires are obsfucated.

Orchestrator methods are:

• create_audio() Creates a simple TTS speech request and adds a sound template to it through mastering.

  • Parameters:

  • scriptText * [Required] (str) - Text to synthesize (TTS).

Webhooks

This SDK provides an easy way of verifying apiaudio webhook call security headers. It is highly recommended for you to verify the headers in order to protect your server from any malicious attack.

The method is:

apiaudio.Webhooks.verify(payload, sig_header, secret, tolerance)

It will return true if the header is valid, otherwise it will raise an error. The parameters to pass are; payload being the body object sent by apiaudio, sig_header being X-Aflr-Secret in the request headers sent by apiaudio, secret being your webhook secret (you can get it in apiaudio console) and tolerance being the tolerance in seconds for the header checks, which defaults to 300 seconds.

Logging

By default, warnings issued by the API are logged in the console output. Additionally, some behaviors are logged on the informational level (e.g. "In progress..." indicators during longer processing times). The level of logging can be controlled by choosing from the standard levels in Python's logging library.

• Decreasing logging level for more detailed logs:

  apiaudio.set_logger_level("INFO")
  # apiaudio.set_logger_level("CRITICAL") - set the highest level to disable logs

Development

There is a pre-commit hook that will run before you commit a file. This is to keep the code standards high. To enable it, you should run make. Then it will set up the pre-commit hook for git. Thats all! Now every time before you commit, it will run to tell you about the standards.

If you use VSCode for committing files, you may bump into pre-commit command not found error. That is ok, just run brew install pre-commit or your fave package manager from the list here.

If you bump into your pip version is old error, just ignore it and use the terminal.

If there is a problem and you are in a rush, you can add --no-verify at the end of the commit command, it will skip the pre-commit hooks, e.g git commit -m 'your commit message' --no-verify
