hello,
im trying to achive web microphone streaming
i have stremalit app in linux server that doesnt have mic, so im tying to use web microphone without success…
is there any way to achive my goal?

here is the code:

import streamlit as st
from streamlit_webrtc import webrtc_streamer, WebRtcMode, ClientSettings
import azure.cognitiveservices.speech as speechsdk
import numpy as np
import av
import threading


speech_config = speechsdk.SpeechConfig(subscription=speech_key, region=service_region)
audio_stream_format = speechsdk.audio.AudioStreamFormat(samples_per_second=16000, bits_per_sample=16, channels=1)
audio_input = speechsdk.audio.PushAudioInputStream(audio_stream_format)
audio_config = speechsdk.audio.AudioConfig(stream=audio_input)
recognizer = speechsdk.SpeechRecognizer(speech_config=speech_config, audio_config=audio_config)

# WebRTC Client Settings (updated)
rtc_configuration = {"iceServers": [{"urls": ["stun:stun.l.google.com:19302"]}]}
media_stream_constraints = {"audio": True, "video": False}

# Initialize session state
if 'recognized_text' not in st.session_state:
    st.session_state['recognized_text'] = ""

def audio_callback(frame: av.AudioFrame) -> av.AudioFrame:
    audio_data = frame.to_ndarray()
    audio_data = audio_data.mean(axis=1).astype(np.int16).tobytes()  # Convert to mono, int16
    audio_input.write(audio_data)
    return frame

def recognize_continuously():
    while True:
        result = recognizer.recognize_once()
        st.session_state['recognized_text'] = "Recognized: {}".format(result.text)

st.title("Streamlit Web Microphone to Azure Speech SDK")

webrtc_ctx = webrtc_streamer(
    key="speech-recognition",
    mode=WebRtcMode.SENDRECV,
    rtc_configuration=rtc_configuration,
    media_stream_constraints=media_stream_constraints,
    audio_processor_factory=lambda: audio_callback,
)

if st.button("Start Recognition"):
    recognition_thread = threading.Thread(target=recognize_continuously)
    recognition_thread.start()

# Display the recognized text from session state
st.write(st.session_state['recognized_text'])

Hi @nikmere

Perhaps you can look into client side implementation to take audio from microphone input. Here’s a thread on this using HTML5
