How Hosiqo compares and tests toolsFinal recommendation
Shortlist Carbon Voice when replacing status meetings and calls with async voice messages that get auto-transcribed and summarized matters most, and Rilla when coaching field reps asynchronously across many appointments matters most. Try them side by side on real calls before deciding — needs vary by team.

Speech analytics and AI coaching platform for in-person field sales that replaces traditional ridealongs with recorded, analyzed conversations.
Carbon Voice is an asynchronous voice-messaging and voice-notes app for iOS, Android, Web, and Apple Watch. Users record voice memos or messages with a single keystroke or swipe, and every message is automatically transcribed so it can be read, searched, labeled, and organized. The app is built around reducing real-time meetings and calls: instead of scheduling synchronous time, teammates exchange voice messages that the recipient can catch up on later. Layered on top is a large library of AI actions that turn raw voice into structured content — bulleted summaries, cleaned-up transcripts (removing filler words and fixing grammar), meeting notes, agendas, action items, professional emails, and longer documents such as PRDs and reports. Users can also query an AI assistant about any chat. A Global Voice feature can translate messages between languages, and messages can be sent to people who don't have the app via a secure email link. It is aimed at distributed teams, managers, and individuals who prefer talking over typing.

Rilla is a speech analytics and AI coaching platform built for in-person field sales teams, particularly in home services and the trades. Instead of managers physically accompanying reps on ridealongs, reps record their in-person sales conversations, and Rilla automatically transcribes and analyzes each conversation to surface insights, summaries, and coaching opportunities. Managers gain visibility into conversations across their team and can review recordings, leave comments and highlights, and deliver asynchronous feedback from anywhere, which lets them coach far more appointments than in-person ridealongs would allow. The platform adapts to a team's specific sales process and can highlight how reps' conversations compare to the behaviors of top performers, helping standardize what works. Rilla serves field-sales-heavy industries including home improvement and remodeling, HVAC, plumbing, roofing, solar, automotive, dental, senior living, and multifamily property management. It is designed for sales managers and field reps who need a scalable way to capture, review, and coach face-to-face selling conversations that conventional meeting tools built for video calls do not address. Pricing varies by plan. Check the official website for current pricing.
