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
