Event structure using voices in your application

You can specify the voice ID in the audioOutputConfiguration when starting a prompt in the promptStart event:

"event": {
        "promptStart": {
            "promptName": "string",
            "audioOutputConfiguration": {
                "mediaType": "audio/lpcm",
                "sampleRateHertz": 16000,
                "sampleSizeBits": 16,
                "channelCount": 1,
                "voiceId": "tiffany",
                "encoding": "base64",
                "audioType": "SPEECH"
            }
        }
    }

Multilingual support

Amazon Nova 2 Sonic provides powerful multilingual capabilities that enable natural conversations across multiple languages. The service supports both polyglot voices (speaking multiple languages) and code-switching (mixing languages within the same sentence), allowing you to build truly global conversational applications.

The TIFFANY (en-US, female) and MATTHEW (en-US, male) are unique polyglot voices that can speak all supported languages:

1. English

2. French

3. Italian

4. German

5. Spanish

6. Portuguese

7. Hindi

This makes Tiffany and Matthew ideal for applications that need to switch between multiple languages seamlessly.
