About

SpeechData.ai is a commercial catalogue and collection service for conversational speech data used to build and evaluate ASR, TTS and other voice-AI systems. Its website lists 60 conversational datasets across 60 languages and dialects, totaling 73,000 audio hours from 7,250 speakers. Listings describe spontaneous two-person recordings, dual-channel audio, time-aligned human-verified transcripts, speaker metadata and consent documentation, with catalogue prices of USD 60–95 per audio hour. Buyers can request samples and commission additional collection to a brief. The provider also offers transcription and audio annotation. Typical buyers include teams sourcing speech for model training and evaluation. Dataset availability, licensing and final price depend on language, collection scope and the terms agreed for the project.

About

Voxtral TTS is a state-of-the-art, multilingual text-to-speech model designed to generate highly realistic and emotionally expressive speech from text, combining strong contextual understanding with advanced speaker modeling to produce natural, human-like audio output. Built as a lightweight model with around 4 billion parameters, it delivers efficient performance while maintaining high quality, enabling scalable deployment for enterprise voice applications. It supports nine major languages and diverse dialects, and can adapt to new voices using only a short reference audio sample, capturing not just tone but also rhythm, pauses, intonation, and emotional nuance. Its zero-shot voice cloning capabilities allow it to replicate a speaker’s style without additional training, and it can even perform cross-lingual voice adaptation, generating speech in one language while preserving the accent of another.
