How Hosiqo compares and tests toolsFinal recommendation
Shortlist Exec when practicing cold calls, discovery, and objection handling safely 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.

Exec is an AI roleplay and training platform designed to help sales reps, leaders, and support staff practice high-stakes conversations before they happen with real customers. Its core function is generating voice-based AI characters that simulate buyers and other counterparts, complete with industry context and customizable traits, so reps can rehearse cold calls, discovery, negotiation, and objection handling in unscripted, dynamic conversations. The platform supports custom scenario creation and includes screen-sharing functionality so reps can practice product demos and presentations, not just talk tracks. After each roleplay, Exec provides instant performance insights, including actionable improvement tips and an AI coach that can explain scores, surface growth areas, and run short follow-up sessions to work through specific gaps. For managers and enablement teams, Exec offers analytics dashboards tracking skill development over time, performance trending, leaderboards, certification, and integration with existing learning management systems. It maintains SOC 2 Type II certification and states it does not use customer data to train its models. Exec is aimed at enterprise sales and revenue teams that want to close the gap between training content and real behavior change through repeated, measurable practice. Pricing varies by plan.

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.
