Where the data runs short.
Voice consent
A TTS voice is a copy of a real person’s voice. Speakers must understand that and agree to it in writing and on record.
Tone and pronunciation
Tonal languages need prompts and transcripts with tone marks, or the voice sounds wrong.
Clean audio
TTS needs quiet rooms and steady microphones, unlike ASR, which benefits from real-world noise.

Consenting workplaces
Each workplace is registered in person by a TrustAm field agent, with the owner’s consent and a location fence.

A spoken challenge code, motion sensors and GPS show each clip was filmed live, at work. No camera-roll uploads.

Buyers usually ask.
Can speakers withdraw consent for a TTS voice?
Speakers can withdraw from future use. Withdrawn recordings are excluded from later deliveries and buyers are asked to delete them, as our licence summary sets out. We explain this to speakers and buyers before recording.
Do you use professional voice actors?
We audition everyday speakers and people with presenting or radio experience. You choose from short auditions before we record at length.
