How Hosiqo compares and tests toolsFinal recommendation
Shortlist EvaluAgent when automatically score and audit 100% of customer service calls and chats for quality and compliance matters most, and WhisperLiveKit when building privacy-first transcription into custom applications via compatible apis matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

EvaluAgent is a UK-based quality assurance and performance-improvement platform built for contact centers, BPOs, QA leads, team managers, and frontline agents. It captures interactions from connected CCaaS, CRM, and helpdesk systems, then transcribes voice calls to text and processes chats, emails, and tickets so every conversation can be reviewed rather than just a manual sample. Its AutoQA engine uses customizable drag-and-drop scorecards to automatically evaluate interactions, applying auto-fail logic and weighting that mirror how a team grades quality. A conversation-intelligence layer adds sentiment analysis, reason-for-contact classification, intent detection, summarization, predictive metrics, and customer-vulnerability signals. Insights flow into coaching plans, performance tracking, and agent feedback. The platform also offers AI-agent observability to detect issues in automated conversations, plus calibration and reporting tools. It integrates with systems such as Genesys, Five9, NICE CXone, Talkdesk, Amazon Connect, Salesforce, and Zendesk, and lists enterprise security credentials including SOC 2 Type II and ISO 27001.

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.
