How Hosiqo compares and tests toolsFinal recommendation
Shortlist Airspeed when revenue teams wanting every call scored and connected to account history matters most, and WhisperLiveKit when building privacy-first transcription into custom applications via compatible apis matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

Airspeed, formerly known as Glyphic, is a sales conversation intelligence and revenue-team platform that records, transcribes, and analyzes calls and connects them with email and ticket history into a persistent memory of each customer account. It integrates with meeting platforms such as Zoom and Teams to capture conversations, then surfaces key themes, generates pre-call and post-call intelligence, and provides contextual answers about accounts grounded in actual interactions. For coaching, Airspeed identifies coachable moments with specific post-call scorecards, tracks metrics like talk-to-listen ratio against team benchmarks, delivers automated coaching plans before standups, and offers a practice simulator with buyer personas to build specific skills such as pricing-objection handling and champion building. It scores live calls during conversations and tracks rep improvement over time. On the workflow side, Airspeed auto-syncs data to Salesforce, HubSpot, and Outreach, works within Gmail, Outlook, and Slack, and uses agents that detect signals like champion changes or stalled deals to draft outreach for rep approval and maintain CRM hygiene. The company is based in London and New York and rebranded from Glyphic to Airspeed in 2026; it is a live, operating product. Pricing varies by plan. Check the official website for current pricing.

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.
