Feature-by-feature
Soniox delivers a unified API combining real-time STT, TTS, and speech translation across 60+ languages and 3,600 language pairs, with sub-200ms latency, multi-speaker diarization, and code-switching support. Its v5 update improved accuracy, speaker separation, and endpointing. Wispr is a desktop-only tool for macOS that offers 97 languages via on-device Whisper or NVIDIA Parakeet models, activated by a global hotkey. It lacks translation, TTS, multi-speaker features, and cloud processing. Soniox adds voice cloning from few seconds of audio, while Wispr’s open-source nature (MIT) allows customization. For enterprise compliance, Soniox has SOC 2 Type 2, ISO 27001, HIPAA, and GDPR; Wispr’s local processing inherently avoids data privacy issues but has no compliance certifications.
Pricing compared
Soniox uses token-based pricing, roughly 8–10x cheaper than major cloud providers (e.g., $0.12/hour for real-time STT). There is no free tier mentioned, so costs depend on usage volume. Wispr is completely free, supported by donations, and open source. For small-scale personal use, Wispr is unbeatable. For businesses processing hours of audio daily, Soniox’s volume pricing could be far more cost-effective than alternatives but still requires paid commitment. Wispr’s lack of cloud sync and limited integration may incur indirect costs (e.g., manual workflows).
