Detailed Review
Voxist SAS is a company based in Paris, France, and its site footer names it as Voxist SAS. The About page says the company was founded in Paris and has worked on voice since 2016.
Voxist sells several products, from voicemail and meeting memos to a contact-centre platform. The Voxist API is the developer product and exposes speech recognition, translation and voice synthesis in one place.
What does the Voxist API offer?
The Voxist developer page lists streaming and batch speech recognition in 40+ languages with automatic language detection. It also lists translation across 1600+ language pairs and neural voice synthesis in 40+ languages.
A voice-to-voice endpoint chains recognition, translation and synthesis, and Voxist quotes perceived latency under one second for it.
How is the Voxist API priced and hosted?
The free plan includes 5 hours of audio a month at 5 requests a second. Pay-as-you-go costs EUR 0.006 per minute billed per second with a 99.9% SLA, and Enterprise is custom.
Voxist says it hosts on OVHcloud and Scaleway exclusively in EU data centres, and that audio sent through the API is not used for model training.
Voxist as a European alternative to Deepgram
Voxist suits teams that want euro billing and French-language accuracy, where Voxist claims a 4.2% word error rate on French. That figure is Voxist's own claim, not an independent test.
Deepgram is stronger where English-language volume, a large developer community and contact-centre case studies matter. See also Speechmatics for a wider rate card.
Limitations to Consider
SOC 2 Type II and ISO 27001 are listed as in progress, not completed. The French accuracy figure is a vendor claim, and the homepage lists English, French, German, Spanish and Italian as recognition languages, so Dutch and Nordic coverage should be tested. The free plan is limited to 5 requests a second and 5 hours a month.
Who Should Use Voxist
French and EU developers who need a free tier, euro invoices and EU hosting for transcription plus translation.
