How Hosiqo compares and tests toolsFinal recommendation
Shortlist Aircall when running outbound and inbound sales calling with ai transcription matters most, and WhisperLiveKit when building privacy-first transcription into custom applications via compatible apis matters most. Try them side by side on real calls before deciding — needs vary by team.
Cloud phone and call center platform with built-in AI conversation intelligence: transcription, call summaries, sentiment, and call scoring.

Aircall is a cloud-based phone and call center platform widely used by sales and support teams, with an integrated AI conversation intelligence layer that runs across calls rather than as a separate bolt-on system. Its core function is to handle business calling through features like power dialing, call recording, IVR, queueing, and routing, while Aircall AI transcribes conversations and analyzes them for insights. The conversation intelligence capabilities include AI-generated call summaries, key topic recognition, sentiment analysis, talk-to-listen ratios, transcription text search, and call scoring, which together help teams spot coaching opportunities and understand customer objections and buying signals. Aircall centralizes communications in a Workspace that brings voice, text, voicemail, and WhatsApp into a threaded view around each customer, with access to recordings and transcripts. The platform logs activity and transcripts to connected CRMs, and an analytics add-on extends dashboards with advanced filters, longer history, and KPI drill-downs. Aircall is aimed at sales and customer-facing teams that want a reliable cloud phone system with conversation intelligence included, rather than running a separate dialer and analysis tool. 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.
