What is Tunk?
Tunk is an AI‑powered voice and speech‑intelligence platform that turns spoken language into text and actionable insights at scale. It offers automatic speech‑to‑text transcription for pre‑recorded audio, real‑time speech‑to‑text APIs, and a Voice AI Agent that can handle inbound and outbound phone‑call conversations similar to a human operator. The platform supports multiple languages and dialects, with features such as speaker diarization, forced alignment, and translation, making it suitable for enterprises that need to analyze calls, meetings, earnings reports, and customer support interactions.
The core value of Tunk lies in its ability to automate documentation and analysis of spoken content while maintaining high accuracy and low latency. You can ingest long or multi‑speaker recordings, get clean, timestamped transcripts, and then use tools like the Anya chatbot to ask questions about the content, extract summaries, or drill into specific topics. This is especially useful for finance, legal, media, and customer‑service teams that deal with large volumes of audio and need fast, searchable records.
Tunk is designed for developers, product teams, and operational units in mid‑ to large‑size organizations that want to integrate speech‑intelligence capabilities into their workflows via APIs or a self‑serve web portal. Developers use the real‑time and batch speech‑to‑text APIs to build voice‑enabled features, while business users can upload files and use the playground or Voice AI Agent to simulate agents handling customer calls, collecting leads, or providing support. The platform positions itself as an enterprise‑grade solution where accuracy, language breadth, and integration depth matter more than a simple consumer‑style transcription app.
Tunk pricing
Pricing model: Free
Tunk offers a free trial with a limited number of free minutes or credits to test the platform, after which usage is billed on a pay‑as‑you‑go basis per minute of audio processed. Pricing is visible when you upload files and select a turnaround time option, with different rates for fast vs standard turnaround and different tiers for speech‑to‑text versus real‑time or Voice AI Agent usage. The platform does not advertise a traditional fixed‑monthly plan for small users; instead, it uses usage‑based billing with the option to contact sales for custom enterprise packages and volume discounts. Refunds are allowed within a short window if the service is inaccessible or if transcriptions are deemed significantly incomplete or inaccurate.

Frequently asked questions about Tunk
What types of files can I transcribe with Tunk?
You can upload common audio and video file formats such as MP3, WAV, M4A, MP4, and similar containers, and Tunk will convert the spoken audio into a timestamped text transcript while preserving speaker separation where possible. The system is optimized for clear speech from calls, meetings, interviews, lectures, and earnings‑call recordings, and supports both mono and multi‑channel recordings.
Does Tunk support real‑time transcription for live calls?
Yes, Tunk provides a real‑time speech‑to‑text API that streams audio as it is spoken and returns text in near real time, which is intended for use with live phone calls, call‑center integrations, or voice‑enabled applications. This API is designed to balance latency and accuracy so you can display or process transcripts while the conversation is still ongoing.
How accurate is Tunk’s speech‑to‑text output?
Tunk emphasizes high‑accuracy transcription across multiple languages and accents by combining multiple transcription engines and additional post‑processing, and the site highlights that its accuracy is suitable for enterprise use cases such as finance and legal. Accuracy can vary depending on background noise, speaker quality, and overlapping speech, but the platform offers tools to correct and refine transcripts and supports human‑assisted review workflows for critical content.
What is the Voice AI Agent and what can it do?
The Voice AI Agent is an AI‑driven phone agent that can make and receive calls, converse with callers, collect information, book appointments, qualify leads, and route issues to the appropriate human team. It is intended for automating customer support, sales outreach, and appointment‑scheduling workflows over the phone while integrating with internal systems such as CRMs and ticketing tools through APIs.
Can I use Tunk via an API inside my own application?
Yes, Tunk exposes speech‑to‑text and real‑time APIs that developers can integrate into their applications, websites, or call‑center infrastructure to automatically transcribe and analyze audio content or trigger downstream workflows. The API docs explain auth, endpoints, request formats, and response schemas so you can build voice‑enabled features without maintaining your own speech‑recognition stack.
How does Tunk handle multiple speakers in a conversation?
Tunk uses speaker diarization to identify different voices in a conversation and label each segment with a speaker identifier, so you can see who said what in a transcript. This helps in scenarios like meetings, interviews, or support calls where keeping track of participants is important for analysis and follow‑up.
Does Tunk provide translation of transcripts?
Yes, the platform supports translation of transcripts into multiple languages, allowing you to make content accessible to global audiences or teams that work in different language regions. Translations are generated from the original speech‑to‑text output and can be used for internal reporting, subtitles, or sharing with non‑native‑speaker stakeholders.
How is Tunk different from generic transcription tools?
Unlike generic consumer‑focused transcription apps, Tunk is built for enterprise‑grade use with features such as multi‑language support, diarization, forced alignment, translation, and Voice AI Agents that can actively participate in phone calls. It also exposes APIs and developer tools, making it suitable for integration into complex workflows in finance, legal, customer support, and media organizations.
What happens after my free trial credits run out?
Once your free demo credits are exhausted, further transcription and API usage are billed according to the pay‑as‑you‑go pricing schedule shown when you upload files or invoke the API. You can continue using the platform by adding payment details, and for heavy usage you can contact sales to discuss custom plans or volume discounts tailored to your organization’s needs.
How does billing and payment work on Tunk?
Tunk charges per minute of audio processed, with the exact rate depending on the service type, turnaround time, and deployment context, and you are billed only for what you use. Payments are processed through the platform’s billing system, and you can view usage history and invoices from your account dashboard; refunds are allowed within a short grace period if the service is inaccessible or the transcription quality falls below the advertised standards.
