How Hosiqo compares and tests toolsFinal recommendation
Shortlist Felo Subtitles when following and translating multilingual video meetings on zoom, google meet, teams, or webex in real time matters most, and Soniox when building voice agents and dictation features into apps matters most. Run both through a week of actual calls to see which suits your workflow.

Multilingual speech AI platform offering real-time and async speech-to-text and translation APIs for meetings and voice apps.
Felo Subtitles, made by Felo Inc. (Sparticle), is a real-time transcription and translation tool delivered as a Chrome/Edge browser extension plus companion desktop apps for Windows and macOS. It listens to meeting and video audio, recognizes speech, and overlays live captions with instant translation into other languages, so participants can follow conversations across language barriers. The browser extension captions web-based audio such as Google Meet (web), YouTube Live, Twitch, and Facebook Live, while the separate Felo desktop app extends coverage to Zoom, Microsoft Teams, Webex, and Tencent Meeting without a bot joining the call. It recognizes speech in roughly 23 languages and translates into about 20 target languages. Captured sessions can be saved as transcripts and exported as text, and the tool offers AI summaries using templates for contexts like sales, learning, and one-on-ones. Custom speech and translation dictionaries let teams add industry terminology. It is aimed at IT, research, HR, legal, education, and video-creator users needing multilingual meeting communication.

Soniox is a multilingual speech AI platform that provides speech-to-text, translation, and text-to-speech APIs aimed at developers building voice-enabled applications, including meeting transcription, voice agents, dictation, and call-center tools. Its speech recognition supports real-time streaming with low latency as well as asynchronous processing of recorded files, and it covers a broad set of languages with the ability to handle conversations where speakers switch languages mid-sentence. For meeting and multi-party scenarios, Soniox offers speaker separation so transcripts can attribute speech to individual participants, along with handling of names, alphanumerics, and domain-specific terms. The platform also includes real-time speech translation across many language pairs, which is useful for international calls and meetings. Soniox markets enterprise-grade compliance, including SOC 2 Type 2, ISO 27001, HIPAA, and GDPR, and offers multi-region deployment with data-residency options and a privacy-oriented architecture where audio is processed in real time. Because it is delivered as APIs and SDKs, organizations typically embed Soniox into their own products rather than using it as a standalone meeting application. Pricing varies by plan. Check the official website for current pricing.
