  • Australian: Polly.Nicole (female), Polly.Russell (male)
  • American: Polly.Joanna (female), Polly.Matthew (male)

Premium Voice (ElevenLabs - Optional):

• ELEVENLABS_API_KEY - Your API key from elevenlabs.io (required to enable ElevenLabs)
• ELEVENLABS_VOICE_ID - Voice ID (required to select which voice)
  • Default: pNInz6obpgDQGcFmaJgB (Adam - clear neutral male)

How It Works

1. No ElevenLabs key → Uses AWS Polly (free, instant)
2. ElevenLabs key set → Uses ElevenLabs voices (premium, natural)
3. ElevenLabs fails → Automatic fallback to Polly
