How Hosiqo compares and tests toolsFinal recommendation
Shortlist Voiso when quality assurance and compliance teams reviewing transcribed, keyword-flagged calls matters most, and oTranscribe when academic and qualitative researchers transcribing fieldwork or oral-history recordings matters most. Run both through a week of actual calls to see which suits your workflow.

A free, open-source web app that eases manual transcription of recorded interviews by integrating media playback controls beside a text editor.
Voiso is a cloud-based contact-center platform built for sales and customer-service teams, combining voice, SMS, and messaging channels with AI-driven analytics in a single workspace. Its speech analytics suite processes recorded call audio through speech-to-text and natural-language pipelines, transcribing calls into searchable text across more than ten languages, including English, Spanish, French, and Arabic. Transcripts can be navigated, searched, and flagged against predefined or custom keyword lists to support quality assurance, compliance, and agent training. Beyond raw transcription, the platform applies AI to score conversations on a 1-to-5 scale, detect sentiment and emotional cues, and automatically generate concise call summaries that capture key topics and outcomes without reviewing full recordings. It is aimed at call centers, BPOs, and outbound and inbound teams in industries such as fintech, travel, retail, and e-commerce. Other platform capabilities include a predictive dialer, IVR and routing flow builder, CRM integrations, call recording, and real-time performance dashboards. Speech analytics features are available on its Pro plan and higher.

oTranscribe is a free, open-source (MIT license) web app, created by Elliot Bentley and maintained by the MuckRock Foundation, that takes the pain out of transcribing recorded interviews. It runs in the browser on desktop computers and places an integrated audio or video player alongside a text editor, so you can pause, rewind, and fast-forward your recording using keyboard shortcuts without taking your hands off the keys or switching between apps. It is built for journalists, researchers, oral historians, and students who type up interviews and recordings themselves. Rather than using automatic speech recognition, oTranscribe assists manual transcription: you listen and type, inserting interactive timestamps (Ctrl+J) that you can click to jump back to that moment in the media. Your transcript autosaves to the browser's local storage, and audio files never leave your computer, keeping work private. Finished transcripts can be exported to Markdown, plain text, or oTranscribe's own .otr format, or sent to Google Drive. Rich-text formatting and adjustable playback speed are supported.
