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 JustCall when reps getting live on-screen objection-handling prompts during calls matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Cloud communications platform with AI call scoring, real-time agent assist, and conversation intelligence for sales coaching across voice and SMS.
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.
