Hi @fgmustang ,
Welcome to Google Cloud Community!
The issue you’re facing with your Python script for Google Cloud Speech-to-Text appears to be specific to processing Spanish audio.
Here’s a summary of the problem:
- Your script functions perfectly with the English (en-US) language code.
- When you switch to Spanish codes (es-MX, es-US, es-VE), it intermittently fails, often around the 4-minute mark (streaming_limit), but can occur anywhere from 15 seconds to 10 minutes.
- Short sentences with pauses tend to perform better in Spanish.
- You occasionally see the error message “Internal error encountered.”
Possible Cause:
- Limited Support for Spanish Dialects: Google STT may have restrictions in processing certain Spanish accents or dialects compared to English, leading to increased processing times and potential timeouts.
- Network Issues: An unstable internet connection could interrupt the streaming process.
- Resource Constraints: While unlikely based on your usage, limited resources on Google’s end might result in occasional errors.
Potential Solution:
- Simplify Audio Input: Aim to reduce the complexity of your Spanish audio. Speak clearly, minimize background noise, and use shorter sentences with breaks if possible.
- Adjust Streaming Limit: If failures often occur around the 4-minute mark, try increasing the streaming_limit in your script to allow for more processing time.
- Ensure Stable Network Connectivity: Check that you have a reliable internet connection to reduce potential interruptions.
- Monitor Google Cloud Status: Regularly check Google Cloud’s status dashboard for any reported issues with Speech-to-Text services.
Additional Tips:
- Some audio inputs may contain multiple languages, e.g. “Hinglish” (Hindi and English) or “Spanglish” (Spanish and English). While Speech does not officially support such inputs, oftentimes the models are able to understand.
- Review the Google Cloud documentation for any known limitations related to Spanish language codes in Speech-to-Text.
- If the issue persists, I suggest filling a feature request so that our Engineering Team can look into it. Note that there’s no definite date as to when this will be implemented. You may keep an eye on the release notes for any latest updates or new features related to Speech to text.
I hope the above information is helpful.
