## Executive Summary
Open TTS Leaderboard: Scalable Evaluation for Multilingual Text-to-Speech and Voice Cloning.

## Why It Matters (Strategic Analysis)
Replacing manual human arena voting with objective WER and RTFx metrics provides reproducible benchmarks for speech intelligibility, inference speed, and voice preservation. This reduces evaluation overhead for open-weights models attempting to benchmark trade-offs directly against closed commercial APIs.
