Why voiceOne

Why your own AI voice?

Because generic voices are interchangeable. And because brand management starts at the first hello.

Brand from second 1

The voice is the first thing your customers hear. With Custom Voice you sound like YOU — not like 1.000 other AI providers.

Personality made to measure

Likeable, professional, relaxed, refined — the voice is trained to your brief. Regional colouring (e.g. Bavarian, Swabian) is also possible.

Consistency across channels

Phone, IVR announcements, voicemail footers, adverts, podcast intros — one voice for everything. Brand identity stays consistent throughout.

Fast to a result

30 minutes of audio material is enough. With a professional speaker: 1 studio session. With a self-recording: 1 day. Training time: 7-10 days.
