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 Koncert when managers coaching reps from recorded calls and a remote salesfloor matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

AI sales dialer with call recording and conversation intelligence, plus an AI PitchLab roleplay add-on for cold-call practice.
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.

Koncert is a B2B sales engagement platform built around AI-powered dialing, call recording, and coaching for outbound teams. Its dialer suite includes options such as an AI Parallel Dialer and an AI Flow Dialer that filter voicemails and connect reps to live answers to increase connected conversations and connect rates. Calls are recorded and run through conversation intelligence that scans for objections and other signals so managers can coach reps at scale, and a remote Salesfloor gives managers a virtual workspace for real-time coaching during calls. Koncert also includes a multi-channel cadence sequencer spanning phone, email, video, text, and social, plus caller ID management that selects local numbers and monitors number health. For practice and training, Koncert offers AI PitchLab, an add-on where reps rehearse pitches against AI-powered buyer personas without the pressure of a live prospect, with objection-handling practice and automatic transcription and scoring of performance. Together these capabilities target outbound sales teams, SDRs, and managers who want dialing, real-call analysis, and structured roleplay practice within one platform. Pricing varies by plan. Check the official website for current pricing.
