Speech & Voice Data

Speech and voice data for ASR, TTS and voice AI

Voice models need variety that is hard to find in public data: accents, emotion, natural conversation and clean, consistent recordings. One6 provides both crowd-sourced speech and professional voice talent, recorded to the technical spec your model needs.

What we deliver

Conversational speech

Natural, unscripted dialogue between speakers for speech recognition and conversational AI.

Scripted recordings

Read speech, wake words and command phrases recorded to defined scripts and audio specifications.

Professional voice talent

Voice actors for narration, expressive and emotional speech, character voices and high-quality TTS data.

Accent and dialect coverage

Speakers recruited across accents, ages and regions to reduce bias in voice models.

Common use cases

  • Training and testing automatic speech recognition (ASR)
  • Building expressive text-to-speech (TTS) voices
  • Improving voice assistants on diverse accents
  • Collecting speech for lower-resource languages

How a project works

  1. 01

    Scope

    A short call to understand your model, data requirements, quality bar and timeline.

  2. 02

    Pilot

    A small first batch so you can review real output before committing to volume.

  3. 03

    Scale

    Once the pilot meets the agreed bar, we staff up and deliver in regular batches with ongoing QA.

Frequently asked questions

What audio formats and quality can you deliver?

Sample rate, format, channel setup, noise conditions and metadata are defined in the project spec, and recordings are checked against it before delivery.

Do speakers consent to their voice being used for AI?

Consent and usage terms for every recording are agreed with you during scoping and put in place with contributors before collection begins.
