# TTS General Benchmark

A multilingual Text-to-Speech (TTS) evaluation benchmark covering 11 Indian languages across multiple real-world use cases. The dataset is designed for systematic and repeatable evaluation of TTS systems under both high-quality and telephony bandwidth conditions.

**Total prompts:** 1,815 unique text samples  
**Languages:** 11  
**Evaluation tracks:** High Quality + 8 kHz Telephony  

> This is an **evaluation-only benchmark dataset** intended for testing and comparison — not for model training.

# Dataset Overview

The TTS General Benchmark provides diverse prompts that reflect practical deployment scenarios such as conversational agents, announcements, narration, support calls, and telephony bots. Prompts are curated to test clarity, robustness, pronunciation handling, and expressive capability.

Each prompt is labeled with:

- language
- usecase
- eval_category (evaluation track)

The dataset contains **two independently evaluated tracks** with different prompt distributions.
