Its AI Pro engine provides transcription, live translation, and video captioning for meetings, events, and webinars, and the Boostlingo Events offering delivers continuous AI-translated captions for onsite, hybrid, and virtual sessions. Attendees can access live AI captions through a shared link or QR code without downloading anything, with captions appearing in their selected language in real time, and organizers can set default languages and enable automatic translation so the system streams translated captions throughout a session without manual switching. The platform supports a large number of languages and thousands of language pairs and integrates with major video-conferencing platforms including Zoom, Microsoft Teams, and Webex, as well as in-person and hybrid event setups. Boostlingo continues to expand its AI capabilities, including a more recent AI Interpreter that joins its AI captions and translations features.

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.
