Reproduction

import gradio as gr
from transformers import pipeline
import numpy as np

MODEL_NAME = "distil-whisper/distil-large-v2"
# MODEL_NAME = "openai/whisper-base.en"

transcriber = pipeline(
    "automatic-speech-recognition",
    model=MODEL_NAME,
)

def transcribe(audio):
    sr, y = audio
    y = y.astype(np.float32)
    y /= np.max(np.abs(y))
    return transcriber({"sampling_rate": sr, "raw": y})["text"]

demo = gr.Interface(
    transcribe,
    gr.Audio(sources=["microphone"]),
    "text",
)

demo.launch(
    share=True,
)

Severity

Blocking usage of gradio

[EGAILab]

An easier way to replicate, with "share=True", there's no output; and comment that out, the audio can play back.

import gradio as gr

def repeat(audio): return audio

demo = gr.Interface( repeat, gr.Audio(sources=["microphone"]), "audio", )

demo.launch( share=True, )

It works for me!!! I launched the Gradio demo on the server, and set share=True. Locally, I used "ssh -CNg -L 8003:127.0.0.1:8003 root@60.165.238.46 -p 30949". Now, the audio file uploaded locally can be accessed on the server at: /tmp/gradio/631ef51ffcf620fe0b8d5a90e573830b60c890ef/audio.wav.

Yes issue is fixed in latest version, feel free to close this, thank you.

@EGAILab Hi, I still met a same issue in gradio==4.29.0.

[cageyoko]

I found that the upload delay may be caused by network reasons. When I wait for a while and click submit, the result I want will appear.
