Chariot TTS: Bringing Human-Like Voices to India

Introduction

Chariot is a new text-to-speech engine built in India. It turns written text into natural-sounding speech in English, Hindi, and Hinglish. Unlike older systems that sound robotic, Chariot understands the context of what is being said. This allows it to pronounce names, numbers, and titles correctly without needing extra instructions. It was chosen for the IndiaAI Mission to help build strong local AI models. The system is designed for streaming apps and delivers the first sound in about 75 milliseconds. This speed makes it perfect for voice agents and instant replies.

Benefits

Chariot offers several advantages for developers and businesses. First, it uses contextual intelligence. It knows how to say things like "Dr. Rao" or "2.5 Lakhs" automatically. Users do not need to add special rules for these items. Second, the voices sound very human. There are twelve realistic voices available. They have natural emotion and pacing instead of a flat, machine-like tone. Third, it performs better than many global competitors. Tests show it has a lower word error rate in Hindi and higher speech quality scores. Finally, it is built for speed. The low latency ensures that conversations feel real-time and smooth.

Use Cases

Chariot is ideal for many applications that need clear and fast speech. It works well for voice agents that answer customer questions. It is also great for Interactive Voice Response (IVR) systems used by banks and telecom companies. Developers can use it to create audiobooks, podcasts, or educational content in Indian languages. The streaming mode allows for live conversations where the system speaks sentence by sentence. Because the data stays within India, it is a safe choice for companies that must follow local data laws. It supports simple integration through REST APIs, streaming connections, or WebSockets.

Pricing

Chariot offers flexible pricing in Indian Rupees with no extra fees for currency conversion. There is a free plan that gives 10,000 credits per month and allows two concurrent requests. This plan never expires and does not require a credit card. For more needs, there is a Lite plan at 99 rupees per month for 15,000 credits. The Starter plan costs 499 rupees per month and includes 100,000 credits plus rights for commercial use. Larger teams can choose the Startup plan at 4,999 rupees per month for 1.5 million credits. The Scale plan offers 10 million credits for 29,999 rupees per month. Annual billing saves users about 17% on these costs.

Vibes

The community response to Chariot has been very positive. It has helped over 1,000 builders launch their voice projects. Developers appreciate the ease of use and the high quality of the audio. The fact that it outperforms major global systems in Hindi accuracy is a big win for local users. Many users value the ability to start for free without a credit card. This lowers the barrier to entry for new creators. The low latency is frequently praised as a key feature for making voice apps feel responsive and modern.

Additional Information

Chariot was selected under the IndiaAI Mission, a government initiative to develop foundational AI models in the country. This partnership highlights its importance in the local tech ecosystem. The company ensures that all data processing happens within India. This compliance with the Digital Personal Data Protection Act builds trust with Indian users and businesses. The engineering team focused on keeping the Time to First Byte at around 75 milliseconds, which is the lowest in the country. This achievement sets a new standard for speed in text-to-speech technology.
