Murmur is a Windows desktop speech-to-text tool. It is positioned not as a meeting collaboration platform, but as a “dictate anywhere” input tool: place the cursor in a document, chat, email, or any other app, hold Ctrl + Win + Alt while speaking, and the text appears directly at the cursor when you release the keys. It is based on OpenAI Whisper, with the official site claiming 95%+ accuracy, support for 90+ languages, and automatic language detection.
Murmur’s main strength is local processing. Its website clearly states that all audio is processed on the device and that speech never leaves the computer, which makes it appealing for users handling sensitive content, such as lawyers, doctors, and researchers. It also supports CUDA or Vulkan GPU acceleration to improve transcription speed, while smart audio processing helps enhance speech clarity. The limitations are that it is currently only explicitly available for Windows 10 1809 or later, and long recordings and file transcription require upgrading to Pro and using Notebook.
The free version includes 150 transcriptions, along with all AI models, 90+ languages, and input across any application, making it easy to try. Pro Daily costs $0.99/day, while Pro Annual costs $12.99/year, offering unlimited transcriptions and priority support; the annual plan is particularly good value. The official site says Murmur can be downloaded for free from the Microsoft Store and upgraded in-app, but the terms of service also mention that Pro subscriptions are processed by Paddle, so it is worth confirming the actual payment route before purchasing.
Its advantages are an extremely simple workflow, privacy-friendly local processing, cross-application input, low pricing, and suitability for frequent writing, email replies, study notes, interview整理, and professional dictation. Its drawbacks are that no API information is provided, making it unsuitable for teams that need backend batch transcription or enterprise system integration; Chinese support can only be inferred indirectly from “90+ languages” and is not stated separately; and support is limited to Pro priority support and a contact email.
Availability in mainland China is not stated in the main content, and the accessibility of the Microsoft Store, Paddle, or the official website still needs to be tested in practice; payment reliability will depend on the relevant channel. If access or payment is restricted, alternatives include Windows’ built-in voice typing, other local Whisper clients, Buzz, or China-focused options such as iFlyrec and Tongyi Tingwu.
