Google STT stopped working

[aryanvdesh]

Bug Description

It looks like some recent changes might have caused the Google STT plugin to stop working. We recently upgraded the package to the latest version (1.3.8 to 1.3.9)

The logs simply say: resumed false interrupted speech. We tried adding logs inside the STT plugin and it looks like no response was returned from Google's API.

After looking at the commit history for the STT plugin, I was able to get it running by using the source code for the plugin before this commit: 30d1319

Let me know if any other information might be useful, thanks!

Expected Behavior

The Google STT plugin should successfully transcribe speech and return responses from Google's API, as it did in version 1.3.8

Reproduction Steps

stt = GoogleSTT(
    languages="en-US",
    model="chirp_3",
    location="us",
    min_confidence_threshold=0.0,
    enable_word_time_offsets=False,
    credentials_file=os.environ["GOOGLE_APPLICATION_CREDENTIALS"],
)

(with Silero + Turn Detector)

Thanks for reporting the issue! It was indeed a bug introduced by #4155 / me 😅 which should be solved by #4338.

What happened:
Transcripts without word information were silently ignored, even when enable_word_time_offsets was set to False. I have also updated our tests to make sure this is covered for future updates.

For the time being, you can continue using the old version <1.3.9 until next release is cut.

Sounds good, no worries. Thank you!!
