Generate MP3 Audio​

curl -X POST https://developer.nabzclan.vip/api/ai/v1/audio/speech \<br> -H "Authorization: Bearer YOUR_API_TOKEN" \<br> -H "Content-Type: application/json" \<br> -d '{<br> "model": "v1-capa-tts-nabzclan/en-AU-NatashaNeural",<br> "input": "Hello, this is a voice test generated with the Capa text to speech model by nabzclan."<br> }' \<br> --output speech.mp3

JSON/Base64 Mode​

If your app prefers JSON, add ?response_format=json. This returns JSON containing base64 audio instead of a raw binary response.

curl -X POST "https://developer.nabzclan.vip/api/ai/v1/audio/speech?response_format=json" \<br> -H "Authorization: Bearer YOUR_API_TOKEN" \<br> -H "Content-Type: application/json" \<br> -d '{<br> "model": "v1-capa-tts-nabzclan/en-US-GuyNeural",<br> "input": "Hello, this is a voice test generated with the Capa text to speech model by nabzclan."<br> }'

Available Voices​

The first Capa TTS release includes 19 voices across English and Spanish locales. Every voice has a generated MP3 sample in the docs so you can compare tone, pacing, accent, and pronunciation before choosing one.

• English: Australia, Canada, Hong Kong, India, New Zealand, and United States voices.
• Spanish: Argentina, Mexico, Puerto Rico, Spain, and Dominican Republic voices.
• Samples: each voice sample uses the same phrase for easy comparison.
