Overview
Chariot is an AI text-to-speech product that generates speech in English, Hindi, and Hinglish from a single model. It is presented as a developer-facing TTS system for building voice agents, product voiceovers, and other applications where speech needs to sound natural and react to context.
The product emphasizes emotionally and contextually aware output, low-latency streaming, and a workflow that does not require extensive manual text normalization. The site says first audio arrives in about 75 milliseconds and that developers can use REST, streaming, or WebSocket-based delivery depending on the application.
Features
Context-aware speech generation
Chariot positions its output as emotionally and contextually aware, inferring pronunciation and spoken form from surrounding context instead of requiring manual normalization in every prompt.
Low-latency streaming
The site says first audio arrives in about 75 ms and that streaming output begins as it is generated, making it suitable for live applications.
REST, streaming, and WebSocket delivery
The API supports three access patterns: REST for a finished WAV file, streaming for raw 16-bit PCM, and WebSocket for sentence-by-sentence agent output.
Voice catalog with accent and gender filters
The homepage describes twelve studio voices and shows filtering by gender and accent, with English, Hindi, and Hinglish voice output from the same model.
India-hosted processing
The pricing section states that India data residency and DPDP compliance apply, and that processing happens in India on Indian infrastructure.
Use Cases
Real-time voice agents
Build conversational voice agents that need to answer quickly and keep a natural pace, using streaming or WebSocket output for sentence-level delivery.
Marketing and promotional audio
Generate product voiceovers, ads, or social audio in English, Hindi, or Hinglish without manually spelling out every pronunciation detail.
App notifications and transactional speech
Add spoken output to apps or workflows where text needs to be read aloud in a context-sensitive way, such as invoices, notifications, OTPs, or support replies.
Code-mixed Indian-language experiences
Create audio products aimed at Indian-language audiences that need natural code-mixing across English, Hindi, and Hinglish.
