Hello, I am struggling to use Speech SDK from within my python container which I use to deploy my django project. Here is my python code:
async def text_to_speech(self, text):
speech_config = speechsdk.SpeechConfig(subscription=os.getenv('SPEECH_KEY'), region=os.getenv('SPEECH_REGION'))
speech_config.speech_synthesis_voice_name='en-US-AndrewMultilingualNeural'
synthesizer = speechsdk.SpeechSynthesizer(speech_config=speech_config, audio_config=None)
visemes = []
def viseme_received(evt):
visemes.append({"offset" : evt.audio_offset / 10000,"visemeId" :evt.viseme_id})
synthesizer.viseme_received.connect(viseme_received)
result = synthesizer.speak_text_async(text).get()
if result.reason == speechsdk.ResultReason.SynthesizingAudioCompleted:
audio_data = result.audio_data # This is the audio data as a byte array
return audio_data, visemes
else:
print(f"Speech synthesis canceled, reason: {result.reason}")
if result.reason == speechsdk.ResultReason.Canceled:
cancellation_details = result.cancellation_details
print(f"Error details: {cancellation_details.error_details}")
return None, None
To containerize my project I use this Dockerfile and compose.yml (there are also other services in the compose file which are irrelevant here):
FROM python:3.12
ARG DB_NAME
ARG DB_USER
ARG DB_PASSWORD
ARG DB_HOST
ARG DB_PORT
ARG AZURE_OPENAI_ENDPOINT
ARG AZURE_OPENAI_API_KEY
ARG SPEECH_KEY
ARG SPEECH_REGION
WORKDIR /backend
RUN pip install --upgrade pip
COPY ./requirements.txt .
RUN pip install -r requirements.txt
ENV DB_NAME=$DB_NAME
ENV DB_USER=$DB_USER
ENV DB_PASSWORD=$DB_PASSWORD
ENV DB_HOST=$DB_HOST
ENV DB_PORT=$DB_PORT
ENV AZURE_OPENAI_ENDPOINT=$AZURE_OPENAI_ENDPOINT
ENV AZURE_OPENAI_API_KEY=$AZURE_OPENAI_API_KEY
ENV SPEECH_KEY=$SPEECH_KEY
ENV SPEECH_REGION=$SPEECH_REGION
COPY . .
When starting the Django project locally everything works out fine. I also checked that the environment variables are set correctly within the container so that is not the problem. I even wrote a script and executed from within the container which made a call to the azure text to speech REST endpoint which worked (but I need viseme support unfortunately). Whenever the function that I provided is executed I get the following logs from the container.
Exception inside application: Exception with error code:

I tried port mapping in the compose service for both 5000:5000 and 443:443. Did not help unfortunately. What am I doing wrong? Thank you for your help :)

To use the Azure Speech SDK within a Python container for a Django project, you need to ensure that the required dependencies and environment are correctly set up. If you receive the error message "Runtime error: Failed to initialize platform (azure-c-shared). Error: 2176," it indicates that there might be a platform compatibility issue or a missing dependency. To resolve this issue, you can modify the Dockerfile to include necessary dependencies, ensure environment variables are correctly set, perform additional debugging steps such as checking the installation of the libMicrosoft.CognitiveServices.Speech.core.so file and running a simple script using the Azure Speech SDK in the container to isolate the problem, and check for known issues. Please try these steps and see if you were able to get the Azure Speech SDK working in your Docker container.
