Language-Specific Configuration

Hindi Optimization

For Hindi agents, we recommend:

{
  "stt": "elevenlabs-scribe",
  "tts": "sarvam",
  "llm": "gemini-2.5",
  "ttsConfig": {
    "sarvam": {
      "voice": "meera"
    }
  }
}

Assamese Configuration

Assamese has limited provider support:

{
  "stt": "elevenlabs-scribe",
  "tts": "azure",
  "llm": "gemini",
  "ttsConfig": {
    "azure": {
      "voice": "as-IN-YashicaNeural"
    }
  }
}

Multi-Language Agents

Agents can be configured to handle multiple languages:

Set primary language in agent settings
Add fallback languages
Configure language detection sensitivity

System prompt addition:
"You can speak Hindi and English. Start in Hindi, but switch to English if the customer prefers. Ask 'क्या आप हिंदी में बात करना चाहेंगे?' at the start."

Regional Variations

For regional dialects, adjust the TTS voice:

Region	Voice ID	Provider
Mumbai Hindi	mumbai_1	Sarvam
Delhi Hindi	delhi_1	Sarvam
South Hindi	south_1	Sarvam

Best Practices

Test with native speakers before deployment
Use regional greetings (Namaste vs. Vanakkam)
Localize examples in system prompt
Consider formality levels (आप vs. तुम)
