How Hosiqo compares and tests toolsFinal recommendation
Shortlist Athreon when transcribing medical dictation and clinical documentation in hipaa-compliant workflows matters most, and WhisperLiveKit when building privacy-first transcription into custom applications via compatible apis matters most. Run both through a week of actual calls to see which suits your workflow.

Open-source, self-hosted real-time speech-to-text and speaker diarization toolkit with a FastAPI server and web interface, suitable for meeting transcription.
Athreon is a US-based company, operating since 1988, that provides speech-to-text transcription, dictation, and virtual medical scribing services. Rather than purely self-serve software, it uses a hybrid workflow that pairs AI transcription with professional human editors to convert audio and video recordings into accurate, editable, and searchable text, including multi-speaker conversations and focus-group recordings. Audio can be captured several ways: the Athreon mobile dictation app for iOS and Android, telephone dictation requiring no extra equipment, supported PC and handheld recorders (Philips, Olympus, Nuance), and secure file upload to its platform. The service offers EHR and API integrations and connects with existing dictation systems and workflow portals such as InQuiry, Axis Online, and NetScribe. It emphasizes security and compliance, including HIPAA and CJIS support, SSL encryption, GovCloud hosting for law enforcement, and background-checked, US-based staff. Athreon is aimed at organizations in healthcare, legal, law enforcement, insurance, finance, research, government, and media that need certified, court-ready documentation. The company also offers separate cybersecurity services.

WhisperLiveKit is an open-source, self-hosted toolkit for ultra-low-latency real-time speech-to-text and speaker diarization. Rather than naively running Whisper on each audio chunk, it uses state-of-the-art simultaneous-speech research for intelligent buffering and incremental processing, which preserves transcription quality while streaming results with minimal latency. The project ships a complete backend built on FastAPI with WebSocket support, an OpenAI-compatible REST API, a Deepgram-compatible WebSocket protocol, and a simple, customizable HTML and JavaScript web interface that captures microphone audio and streams it to the server. It supports multiple ASR backends including Whisper variants, Voxtral, and Qwen3-ASR, covers 200+ languages with translation, and includes real-time speaker diarization and voice activity detection to reduce processing overhead. It can handle multiple concurrent users on a single backend and is distributed via PyPI with Docker images for both GPU and CPU. Licensed under Apache 2.0 and actively maintained into 2026, the project explicitly lists meeting transcription, accessibility tooling, and podcast or call transcription with speaker identification among its intended use cases, making it a practical building block for private, on-premise meeting transcription pipelines. Pricing varies by plan. Check the official website for current pricing.
