How Hosiqo compares and tests toolsFinal recommendation
Shortlist CAMB.AI when holding multilingual meetings where participants speak different languages and need live voice interpretation matters most, and aTrain when universities and public bodies needing gdpr-friendly local transcription matters most. Run both through a week of actual calls to see which suits your workflow.

Open-source offline transcription tool from the University of Graz that turns recorded meetings and interviews into text using Whisper and speaker detection.
CAMB.AI is an AI voice synthesis, speech translation, and localization platform built on its proprietary MARS (text-to-speech) and BOLI (translation) models, supporting 150+ languages. While much of its product line targets media, sports, and entertainment dubbing through its Studio platform, its Chatterbox desktop application is aimed at live communication: it delivers real-time, bi-directional voice translation so participants speaking different languages can converse in multilingual meetings and customer-support calls. Chatterbox runs as a desktop app on Windows and Mac, translating spoken audio in both directions while aiming to preserve the speaker's voice and tone. The broader platform also offers text-to-speech, captions and subtitles, transcription, and translation features, accessible via a web-based Studio interface and a developer API/SDK (including integrations such as Google Cloud Vertex AI and LangChain). It is suited to globally distributed teams, support organizations, and media companies that need to break language barriers in real-time spoken interactions rather than traditional same-language note-taking.

aTrain is a free, open-source desktop application for offline speech transcription, developed by researchers at the Business Analytics and Data Science Center of the University of Graz in Austria. It provides a graphical interface around OpenAI's Whisper model (via the faster-whisper implementation) so users with no programming experience can transcribe recorded meetings, interviews, lectures, and other audio. Because all processing happens locally on the user's own computer, no audio or text is uploaded to any server, which makes it well suited to privacy-sensitive and GDPR-conscious environments such as universities, public institutions, and research teams. aTrain supports a wide range of languages and adds speaker detection through pyannote.audio so contributions from different participants can be separated. Transcripts can be exported in formats compatible with qualitative-analysis software such as MAXQDA, ATLAS.ti, and NVivo. It runs on Windows (including a Microsoft Store distribution) with GPU acceleration on NVIDIA hardware, and is distributed under the AGPL-3.0 license. It is best for researchers, academics, and organizations that need accurate, local, no-cloud transcription of recorded conversations. Pricing varies by plan. Check the official website for current pricing.
