wave.Error: file does not start with RIFF id

[philuxzhu]

I test the tests/chinese_test.py but there is an error. Does anyone know how to solve it?

Traceback: Traceback (most recent call last): File "/Users/zhujunming/Desktop/AIQQ/tts/RealtimeTTS/RealtimeTTS/text_to_stream.py", line 265, in synthesize_worker success = self.engine.synthesize(sentence) File "/Users/zhujunming/Desktop/AIQQ/tts/RealtimeTTS/RealtimeTTS/engines/system_engine.py", line 72, in synthesize with wave.open(self.file_path, 'rb') as wf: File "/usr/local/Cellar/python@3.10/3.10.13_1/Frameworks/Python.framework/Versions/3.10/lib/python3.10/wave.py", line 509, in open return Wave_read(f) File "/usr/local/Cellar/python@3.10/3.10.13_1/Frameworks/Python.framework/Versions/3.10/lib/python3.10/wave.py", line 163, in init self.initfp(f) File "/usr/local/Cellar/python@3.10/3.10.13_1/Frameworks/Python.framework/Versions/3.10/lib/python3.10/wave.py", line 130, in initfp raise Error('file does not start with RIFF id') wave.Error: file does not start with RIFF id

Maybe the sentence tokenizer messes up.

Let us verify this. To add logging so we can see the text which is sent to the engine:

import logging
logging.basicConfig(level=logging.DEBUG)    
engine = SystemEngine(level=logging.DEBUG)

And then in the play or play_async add this param:

stream.play(log_synthesized_text=True)

Now you should see log message like this in the CLI:

INFO:root:synthesizing: <TEXT>

Is the text displayed correctly there or does the text look messed up?

I have the same problem. I am using macOS Ventura.

Is the text displayed correctly there

Yes. @KoljaB

The problem is, that the format of the file generated by SystemEngine is AIFF instead of wav.

Confirmed. I have tested pyttsx3.save_to_file, it uses aiff format on MacOS and wav format on Linux.

Thank you very much @badbye for pointing this out.

Fix is now available in v0.3.34
