Sarvam

Updated

Integrate Sarvam TTS with the Conversational AI Engine.

Sarvam provides fast, reliable text-to-speech (TTS) with support for Indian languages and customizable voices.

Info

This integration is fully supported for use with Conversational AI Engine. While it has completed functional validation, it is newer to the platform, and additional provider-specific edge cases may be identified as usage scales across a broader range of applications and workloads.

Sample configuration

The following examples show how to configure Sarvam TTS when starting a conversational AI agent.

from agora_agent import Agent
from agora_agent.agentkit.vendors import SarvamTTS

# client is your configured Agora client
agent = (
    Agent(client)
    .with_stt(...)  # configure your STT vendor
    .with_llm(...)  # configure your LLM vendor
    .with_tts(SarvamTTS(
        key='your-sarvam-key',
        speaker='anushka',
        target_language_code='en-IN',
    ))
)
import { Agent, SarvamTTS } from 'agora-agents';

// client is your configured Agora client
const agent = new Agent({ client })
  .withStt(/* configure your STT vendor */)
  .withLlm(/* configure your LLM vendor */)
  .withTts(new SarvamTTS({
    key: 'your-sarvam-key',
    speaker: 'anushka',
    targetLanguageCode: 'en-IN',
  }));
import "github.com/AgoraIO/agora-agents-go/v2/agentkit/vendors"

// client is your configured Agora client
agent := agentkit.NewAgent(client).WithStt(/* configure your STT vendor */).
  WithLlm(/* configure your LLM vendor */).
  WithTts(
    vendors.NewSarvamTTS(vendors.SarvamTTSOptions{
        Key:                "your-sarvam-key",
        Speaker:            "anushka",
        TargetLanguageCode: "en-IN",
    }),
)

Use the following tts configuration in your request:

"tts": {
  "vendor": "sarvam",
  "params": {
    "api_subscription_key": "<SARVAM_API_KEY>",
    "speaker": "anushka",
    "target_language_code": "en-IN"
  }
}
