# Recommended parameters

Starting points to adapt. Every option is described in [`POST /v2/live`](/api-reference/v2/live/init/).

## Voice agents

Fast transcripts, and an answer only when the caller has finished.

```json
{
  "model": "trantoria-1-fast",
  "encoding": "wav/pcm", "sample_rate": 16000, "bit_depth": 16, "channels": 1,
  "language_config": { "languages": ["en"] },
  "endpointing": 0.3,
  "end_of_turn": true,
  "numerals": true,
  "messages_config": { "receive_partial_transcripts": true }
}
```

Answer on [`end_of_turn`](/live/end-of-turn/), not on each final. The [number hold](/live/endpointing/#number-hold)
keeps a dictated card or phone number in one utterance.

## Call centers

Telephone audio, agent and caller on separate channels, personal data redacted.

```json
{
  "model": "solaria-3",
  "encoding": "wav/ulaw", "sample_rate": 8000, "bit_depth": 8, "channels": 2,
  "endpointing": 0.5,
  "pii": true,
  "numerals": true,
  "realtime_processing": { "sentiment_analysis": true },
  "custom_metadata": { "call_id": "..." }
}
```

## Meetings

One microphone, several speakers, whole sentences, your jargon.

```json
{
  "model": "solaria-3-balanced",
  "encoding": "wav/pcm", "sample_rate": 16000, "bit_depth": 16, "channels": 1,
  "endpointing": 0.8,
  "diarization": true,
  "named_entity_recognition": true,
  "realtime_processing": {
    "custom_vocabulary": true,
    "custom_vocabulary_config": { "vocabulary": ["Gladia", "solaria"] }
  }
}
```

## Live captions in several languages

```json
{
  "model": "solaria-3-fast",
  "encoding": "wav/pcm", "sample_rate": 48000, "bit_depth": 16, "channels": 1,
  "language_config": { "languages": [], "code_switching": true },
  "messages_config": { "receive_partial_transcripts": true },
  "realtime_processing": {
    "translation": true,
    "translation_config": { "target_languages": ["en", "fr", "es"] }
  }
}
```
