Azure OpenAI Speech to Speech chat on Raspberry Pi

Question

I am trying to run the Azure OpenAI speech to speech chat example on my Raspberry Pi with 64 bit OS and connected a USB microphone and speaker to it. I installed all the required libraries successfully. However, I am facing some issues. When I run the python code, i get the following error:

Traceback (most recent call last): File "/home/admin/Voice_Assistant/voice_assistant.py", line 27, in <module> speech_synthesizer = speechsdk.SpeechSynthesizer(speech_config=speech_config, audio_config=audio_output_config) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/admin/Voice_Assistant/myenv/lib/python3.11/site-packages/azure/cognitiveservices/speech/speech.py", line 2225, in __init__ _call_hr_fn(fn=_sdk_lib.synthesizer_create_speech_synthesizer_from_config, *[ File "/home/admin/Voice_Assistant/myenv/lib/python3.11/site-packages/azure/cognitiveservices/speech/interop.py", line 62, in _call_hr_fn _raise_if_failed(hr) File "/home/admin/Voice_Assistant/myenv/lib/python3.11/site-packages/azure/cognitiveservices/speech/interop.py", line 55, in _raise_if_failed __try_get_error(_spx_handle(hr)) File "/home/admin/Voice_Assistant/myenv/lib/python3.11/site-packages/azure/cognitiveservices/speech/interop.py", line 50, in __try_get_error raise RuntimeError(message) RuntimeError: Exception with error code: [CALL STACK BEGIN] /home/admin/Voice_Assistant/myenv/lib/python3.11/site-packages/azure/cognitiveservices/speech/libMicrosoft.CognitiveServices.Speech.core.so(+0x850ac) [0x7fb4d850ac] /home/admin/Voice_Assistant/myenv/lib/python3.11/site-packages/azure/cognitiveservices/speech/libMicrosoft.CognitiveServices.Speech.core.so(synthesizer_create_speech_synthesizer_from_config+0x224) [0x7fb4ecdf30] /lib/aarch64-linux-gnu/libffi.so.8(+0x63e0) [0x7fb54563e0] /lib/aarch64-linux-gnu/libffi.so.8(+0x5b24) [0x7fb5455b24] /usr/lib/python3.11/lib-dynload/_ctypes.cpython-311-aarch64-linux-gnu.so(+0x12094) [0x7fb54a2094] /usr/lib/python3.11/lib-dynload/_ctypes.cpython-311-aarch64-linux-gnu.so(+0x1048c) [0x7fb54a048c] python3(PyObject_Call+0x214) [0x4f35f8] python3(_PyEval_EvalFrameDefault+0x4844) [0x4ae2f4] python3(_PyFunction_Vectorcall+0x19c) [0x4e2bcc] python3(PyObject_Call+0xac) [0x4f3490] python3(_PyEval_EvalFrameDefault+0x4844) [0x4ae2f4] python3(_PyFunction_Vectorcall+0x19c) [0x4e2bcc] python3(_PyObject_FastCallDictTstate+0x2e8) [0x49c2f8] python3() [0x4edd44] python3(_PyObject_MakeTpCall+0x1d8) [0x494608] python3(_PyEval_EvalFrameDefault+0x8ec) [0x4aa39c] python3(PyEval_EvalCode+0xb0) [0x4a0c70] python3() [0x5fd9a8] [CALL STACK END] Failed to get HTTP platform singleton instance.

Could someone help me out in troubleshooting this error? What needs to be changed?

@Sashank N Welcome to Microsoft Q&A Forum, Thank you for posting your query here!

Please follow the below action plan:

• Ensure your Raspberry Pi has a stable internet connection and no firewall or network policies are blocking the connection to the Azure service.
• Make sure you are using a supported version of Python and the latest version of the Azure Speech SDK.
• Ensure all necessary dependencies are installed on your Raspberry Pi. You might need to install additional libraries like libssl-dev and ca-certificates.
• Also please enable the Speech SDK logging to get a verbose error log to identify the cause of the issue.
• Try adding speech_config.set_property_by_name("OPENSSL_DISABLE_CRL_CHECK", "true") in your code and check. Though it is not recommended. But it will help in isolating the issue.

.

Suggestions:

• Please be aware that the Speech Devices SDK is now retired.
• The SDK has issues reported on Raspberrian Pi OS in the past. I have seen issues on the SDK issues pages.
• You can however install the supported libraries for windows or linux OS. For example: With the SDK version 1.11.0 binaries for linux ARM32 and ARM64 are released for raspberry pi. You could also try with 1.16.0 SDK version and check. .
• Also, the SDK issues pages here and here are the official support page for issues related to the SDK. I hope this helps.

I hope this helps.
