# Lumoz Instant Voice Cloning & Multilingual TTS v4
Yes! **Lumoz AI natively supports Instant Voice Cloning (`lumoz_clone_voice`) and 90+ language Text-to-Speech (`lumoz_generate_tts`)—including Bengali (`বাংলা`)—directly through MCP.**
## 1. How to Clone a User's Voice in MCP
If the user uploads or provides an audio recording of their voice (10 to 120 seconds of clean speech in MP3, WAV, or M4A):
### Option A: Permanent Reusable Voice Clone (`lumoz_clone_voice`)
1. If the user's audio is a local file or chat attachment, first upload it to Lumoz R2 CDN using `lumoz_upload_media` (pass the base64 data URI).
2. Call `lumoz_clone_voice`:
```json
{
"name": "User Custom Voice",
"audio_url": "https://cdn.lumozai.com/uploads/...",
"remove_background_noise": true,
"sample_text": "লুমোজ এআই ভয়েস ক্লোনিং এখন বাংলায় কথা বলতে পারে।"
}
```
3. `lumoz_clone_voice` returns a permanent white-label `voice_id` (e.g. `"lumoz-voice-user-custom-a8f2k"`).
4. Pass that `voice_id` into `lumoz_generate_tts` for all future voiceovers!
### Option B: 1-Step Instant Clone & Speak (`lumoz_generate_tts` with `reference_audio`)
You can also pass `reference_audio` directly inside `lumoz_generate_tts` (or `lumoz_run_model` with `model_id: "lumoz-tts"`):
```json
{
"text": "[warmly] নমস্কার, এটি আমার নিজের ক্লোন করা কণ্ঠে তৈরি করা হয়েছে।",
"reference_audio": "https://cdn.lumozai.com/uploads/..."
}
```
## 2. Directing Emotion & Merging with Video
- **Inline Emotion Tags**: Use bracketed cues in `text` such as `[whispers]`, `[excited]`, `[calmly]`, `[laughs]`, or `[narrator tone]`.
- **Merging Voiceover into Video**: Once `lumoz_generate_tts` returns the `audio_url`, call `lumoz_run_microservice` with `service: "video-audio-merger"`, `video_url`, and `audio_url` to combine the cloned voiceover with any video!
