how to set Speaking speed on tts?

[eliyahuKriel]

hi guys i able to set voice and lang I want also to change the speed of the voice , i cant find in the docs and in the speechConfig this property

i have this code :

const ttsSdk = require("microsoft-cognitiveservices-speech-sdk");

const speechConfig = ttsSdk.SpeechConfig.fromSubscription(process.env.TTS_SUBSCRIPTION_ID, process.env.TTS_REGION); speechConfig.speechSynthesisVoiceName = selected_voice; speechConfig.speechSynthesisLanguage = selected_lang;

any ideas? thanks!

@eliyahuKriel You can use the "prosody rate" element in SSML to change the speed of the voice, for example:

<prosody rate="-20%">
  I'm speaking a little slowly here
</prosody>
<prosody rate="40%">
  But now I'm speaking really fast
</prosody>

Text to Speech | Microsoft Azure halfway down has a box where you can quickly try things (and boilerplate SSML to modify).

Thanks for using Speech SDK, and taking the time to ask about this feature!

@glharper thanks, i know that i can use the ssml format but i want to use the object format, synthesizer.speakTextAsync and not synthesizer.speakSsmlAsync Too bad there is no such possibility with the object format thanks anyway
