How Hosiqo compares and tests toolsFinal recommendation
Shortlist DubTab when following zoom, google meet or teams meetings in another language with live captions and dubbing matters most, and Zenarate when monitoring customer sentiment and emerging call topics to surface compliance and experience issues matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

Zenarate's Performance Analyzer is an AI tool that transcribes, redacts, and scores live contact-center agent calls for quality assurance and coaching.
DubTab is a browser extension for Chrome and Edge that translates spoken audio in real time as it plays in a browser tab. Rather than requiring file uploads or exports, it listens to the audio of whatever tab is playing and produces live translated subtitles on screen, optional bilingual (original plus translation) captions, and low-latency AI voice dubbing that speaks the translation aloud. The vendor states audio stays in the tab and only text segments are processed, and that translations appear with roughly half-a-second latency suitable for live content. It supports 50+ languages and offers voice selection and volume-ducking controls. Because it works on any site with audio, supported contexts include YouTube, Twitch, Netflix, Udemy, Coursera and Bilibili, as well as meeting and conferencing tools such as Zoom, Google Meet and Microsoft Teams, where it can show what participants are saying in real time. It is aimed at online learners, livestream and international-content viewers, and remote meeting participants who need on-the-fly interpretation and captioning.
Best suited for
Zenarate is an AI simulation-training and conversation-analytics platform for contact centers, and its Performance Analyzer (formerly Call Analyzer) is the module that turns live customer calls into structured quality and coaching data. The AI engine automatically transcribes each interaction, redacts sensitive information, and scores calls against a client's defined call model and skill expectations, processing up to 100% of calls rather than a small sampled subset. Analysis runs nightly so leaders have results the next day, with automated scorecards, sentiment analysis, topic and trend reporting, and next-action coaching recommendations. Managers can drill into specific conversation moments, listen to the audio, and add commentary directly from the scorecard. Because it sits inside Zenarate's AI Coach platform, identified gaps can be turned into personalized roleplay simulations and coaching plans. It is built for QA managers, training leaders, and contact-center operations across industries such as financial services, healthcare, insurance, telecom, retail, and travel, and supports multiple languages and global deployments.
