How Hosiqo compares and tests toolsFinal recommendation
Shortlist Attendee when developers embedding meeting recording and transcription into their own saas products matters most, and Soniox when building voice agents and dictation features into apps matters most. Try them side by side on real calls before deciding — needs vary by team.

Multilingual speech AI platform offering real-time and async speech-to-text and translation APIs for meetings and voice apps.
Attendee is an open-source REST API, developed by Attendee Labs, that abstracts the engineering work of building meeting bots into a single developer-friendly interface. Instead of maintaining separate bot stacks for each video platform, developers send one API request and Attendee dispatches a bot that joins a Zoom, Google Meet, or Microsoft Teams call, then returns recordings, transcripts, and real-time media streams. It is built on widely used, battle-tested technologies such as Django, PostgreSQL, and Redis, and is designed to run from a single Docker image so teams can self-host it on their own infrastructure for data residency, compliance, and cost control. The project documents real-time transcription, webhooks, calendar integration, scheduled meetings, and websocket audio input/output. Because it is open source and self-hosted, organizations in regulated industries can keep meeting audio and transcripts inside their own environment rather than routing them through a third-party vendor. The repository is actively maintained with frequent releases, and the project markets itself as a lower-cost alternative to closed-source meeting-bot platforms for developers who want to embed meeting capture and transcription into their own applications. Pricing varies by plan. Check the official website for current pricing.

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.
