Register Twilio Test Audio

Upload audio files to S3 and register them for use with twilio_place_call.py.

Prerequisites

  • SSH access to server-local with AWS CLI configured
  • Audio file must be in mulaw format (8kHz, mono) for Twilio compatibility

Quick Reference

Item Value
S3 Bucket codel-development-tts-audio
S3 Prefix test-audio/
URL Pattern https://codel-development-tts-audio.s3.amazonaws.com/test-audio/{filename}
Script api/src/scripts/twilio_place_call.py
Dict AUDIO_FILES

Steps

1. Convert audio to mulaw format (if needed)

ffmpeg -i input.wav -ar 8000 -ac 1 -acodec pcm_mulaw output_mulaw.wav

2. Upload to S3 and make public

From server-local (uses --profile codel):

# Upload single file
aws s3 cp /path/to/audio_mulaw.wav s3://codel-development-tts-audio/test-audio/ --profile codel

# Make it publicly readable (required for Twilio to access)
aws s3api put-object-acl --bucket codel-development-tts-audio --key test-audio/audio_mulaw.wav --acl public-read --profile codel

# Verify upload and public access
curl -sI "https://codel-development-tts-audio.s3.amazonaws.com/test-audio/audio_mulaw.wav" | head -1
# Should return: HTTP/1.1 200 OK

3. Update twilio_place_call.py

Add entry to AUDIO_FILES dict:

AUDIO_FILES = {
    # ... existing entries ...
    "newname": "https://codel-development-tts-audio.s3.amazonaws.com/test-audio/audio_mulaw.wav",
}

4. Test the audio

# Verify URL is accessible
curl -sI "https://codel-development-tts-audio.s3.amazonaws.com/test-audio/audio_mulaw.wav" | head -1
# Should return: HTTP/1.1 200 OK

# Test with a call
docker compose exec api python src/scripts/twilio_place_call.py --audio newname --to '+1234567890' --duration-minutes 1

Common Issues

Issue Solution
403 Forbidden Check S3 bucket permissions, file may not be public
Audio doesn't play Ensure mulaw format (8kHz mono)
Call gets error Verify URL returns 200, not 503

Naming Convention

Use descriptive names with _mulaw suffix:

  • fight_mulaw.wav - Conflict/argument audio
  • neutral_mulaw.wav - Normal conversation
  • healthyfight_mulaw.wav - Healthy disagreement
