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 Rehearsal when certifying reps' messaging through reviewer-scored practice attempts matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Video-based roleplay and AI practice platform where sales teams rehearse real-world scenarios and get feedback.
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.

Rehearsal is a video-based practice and roleplay platform, developed by ELB Learning, that gives sales teams and other learners a safe environment to practice their selling and communication skills before high-stakes situations. Learners record video responses to real-world scenarios, build the muscle memory needed to perform under pressure, and receive feedback through multiple practice attempts. The platform pairs traditional video roleplay with AI capabilities: an AI-powered feature evaluates learner video responses and provides automated feedback and assessment metrics, complementing human review from mentors and managers. Rehearsal Coaching supports collaborative, iterative learning by letting reviewers leave feedback and allowing learners to retry until they improve, which is useful for objection handling, pitch delivery, and discovery conversations. While the platform is widely used for sales enablement, it also supports adjacent use cases such as customer support training, leadership development, onboarding, and education. The company, founded by Darik Volpa and based in Reno, Nevada, describes itself as privately held and growing, and Rehearsal maintains a presence on review sites such as G2. It is an established, actively operating product suited to organizations that want structured, repeatable video practice with both AI and human feedback loops. Pricing varies by plan. Check the official website for current pricing.
