Deepslate
Deepslate offers a speech-to-speech model stack for teams building live voice agents—think insurer or utility phone assistants that must listen, reason and reply without stitching separate STT and TTS hops by hand. The product messaging emphasizes multilingual coverage, EU hosting, browser templates, SIP-style phone connections and realtime frameworks such as LiveKit for low-latency sessions. Developers can start with starter credit and then pay per minute as traffic grows, with Enterprise options when concurrency, compliance or custom deployment matter. Pricing is published in euros rather than dollars on the site we reviewed. Limitation: minute-based billing means busy contact-center pilots can spend quickly once the starter credit is gone, and release promotional rates may change. Voice agents still need careful escalation paths and consent handling on recorded lines.
