Chariot

Chariot is an AI text-to-speech tool for English, Hindi, and Hinglish with low-latency streaming and API access for natural-sounding voice apps.

Chariot

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

Single-model multilingual TTS

The product generates speech in English, Hindi, and Hinglish from a single model, which is meant to handle code-mixed text without switching systems.

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.
