Because behind every synthetic voice there is a human being

Synthetic voices in voice assistants and apps are not - as many believe - completely artificially generated voices. Behind them there is always a human being and a complex recording process. This is exactly what we have specialized in. At comevis, we are experts in the field of voice synthesis and offer you extensive know-how, a broad network of speakers, and technology tailored specifically to the application area.

Reach your goal faster with comevis experts

What normally takes up to 10,000 sentences and about 4 weeks of work, we can do in just 300 sentences and 3 to 7 days, for example, thanks to neural language models.

This not only saves time and money, but also gives you the opportunity to make your corporate voice as individual as possible and tailored to the brand. Special tonalities, whispering, shouting, speaking with understanding or encouragement - it's all possible. Stand out from the competition with branded voice marketing and personalize your corporate voice so extensively that it no longer sounds like a synthetic voice, but like real conversation partners.

We bring you together with top speakers

Thanks to our broad network in the voiceover scene, we have exactly the right professional voiceover artists for your corporate voice. Together, we develop fair and transparent contracts and ensure that ethical information on this far-reaching use of the voice is clear and understandable at all times.

The right technique for great voices

Since a recording studio and normal microphones are by far not enough to produce a good synthetic voice, we at comevis work with special technology that guarantees the highest quality. We record your speakers in our specially designed TTS cube and use it to ensure that a voice recorded over several days sounds as if it has been cast in one piece. The cube always ensures the same acoustic conditions with reduced reverberation time and can bring the SSR (signal-to-noise ratio) to -80 dB. This means for you: a clear voice without any noise. For comparison: a normal studio just manages an SSR of 40 to 60 dB.

comevis quality for your voices

Standard quality tests such as an MOS test, in which a subjective quality perception is checked with users, or a WER test (Word Error Rate) are not enough for us. At comevis, we have developed a special test procedure which, among other things, tests the naturalness, tonality and listening effort for users. This is how we ensure that your synthetic corporate voice is at an excellent speech level.
