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)
