How Hosiqo compares and tests toolsFinal recommendation
Shortlist CallMiner when contact centers monitoring agent performance and automating quality scoring and coaching matters most, and Whisperstream when transcribing imported audio recordings privately on-device matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

CallMiner is an enterprise speech and conversation analytics platform, built around its Eureka product, that captures and analyzes customer interactions across voice and digital channels. It records and transcribes calls into text, then applies acoustic and linguistic AI to surface sentiment, emotion, intent, and behavioral signals — quantifying frustration, effort, satisfaction, and confidence rather than sampling a fraction of conversations. Designed for contact centers and large enterprises, it spans modules for analysis, automated agent scoring and coaching, real-time guidance during live calls, automated redaction of sensitive data, multilingual translation, and interactive dashboards. CallMiner ingests voice, chat, email, surveys, social media, and screen recordings, applying scoring models to isolate compliance risks, fraud, quality issues, and sales outcomes. It also includes generative and agentic AI features such as automatic category creation, contact summarization, and natural-language discovery. The platform is used across healthcare, finance, retail, insurance, and BPO sectors, and was named a leader in The Forrester Wave: Conversation Intelligence Solutions for Contact Centers, Q2 2025.

Whisperstream is a downloadable Windows desktop application from Lanreal Technologies Inc. that converts speech to text using push-to-talk dictation. Transcription runs entirely locally on the user's PC via the NVIDIA Parakeet model, so audio is never uploaded to the cloud and no account is tied to the user's voice. It works across any application without add-ins or setup, inserting dictated text directly into tools such as Outlook, Gmail, Slack, VS Code, browsers, and Claude Code. Beyond live dictation, it can import and transcribe existing audio recordings, and it keeps a searchable transcript history with audio replay, encrypted on the device. Additional features include AI cleanup that tidies spoken input, a custom vocabulary for names, jargon, and acronyms, per-app custom AI prompts, support for 25 languages, global keyboard shortcuts, and full offline operation. It requires Windows 10 or 11 (64-bit) with at least 8GB RAM. It targets professionals and privacy-conscious knowledge workers who want fast, local voice input rather than typing.
