Text-to-Speech API
Indian language voice API for developers
Integrate VoisLabs' studio-quality Indian language voices into your IVR, app, or automation pipeline. Simple REST API, low latency, and 12 Indian languages with emotion control. The VoisLabs API is designed for developers who need natural-sounding Indian language TTS without building their own ML pipeline. A single POST request with your text, language, voice, and optional emotion preset returns high-quality MP3 or WAV audio — no complex SDKs, no SSML markup, no vendor lock-in. The API supports all 12 languages (Hindi, Tamil, Telugu, Bengali, Kannada, Malayalam, Marathi, Gujarati, Punjabi, Odia, Urdu, and English) through a unified endpoint, so you do not need separate integrations for each language. For IVR systems, the API delivers sub-500ms responses for short utterances, making it compatible with real-time call flows on Exotel, Knowlarity, Ozonetel, and standard SIP/PSTN platforms. For content automation pipelines, batch endpoints let you submit multiple text segments in a single request and receive stitched audio output. Authentication uses standard API keys with scoped permissions, and usage is metered by audio minutes generated — the same credit system used in the web interface (Creator ₹299 / Studio ₹899 / Pro ₹2,499).

Simple REST API
One POST request to generate audio. No complex SDKs or setup. JSON in, MP3/WAV out.
12 Indian Languages
Hindi, Tamil, Telugu, Bengali, Kannada, Malayalam, Marathi, Gujarati, Punjabi, Odia, Urdu, and English — all via the same API endpoint.
Emotion Control
Pass a preset parameter to apply any of 30+ emotion styles programmatically.
IVR-Ready
Under 500ms latency. Compatible with Exotel, Knowlarity, Ozonetel, and other Indian IVR providers.
Batch Generation
Submit multiple text segments in a single API call. Ideal for generating entire audiobook chapters, course modules, or notification banks in one request without managing individual calls.
Webhook Callbacks
For longer audio generation, register a webhook URL and receive a callback when your audio is ready. No polling required — your system gets notified the moment the file is available for download.
