RocketWhisper

RocketWhisper is a desktop application for speech recognition and transcription based on the OpenAI Whisper engine. It operates completely offline, ensuring audio data remains on the user's computer. It supports NVIDIA (CUDA) GPU acceleration for processing up to ten times faster than a CPU. The tool enables real-time dictation, batch file processing, subtitle export, and integration with language models (LLMs) for intelligent text formatting.

• Offline recognition with Whisper. The application uses the OpenAI Whisper engine to transcribe audio with high accuracy. All processing is done on the local computer, without sending data to external servers, ensuring absolute confidentiality of conversations and audio files.
• NVIDIA (CUDA) GPU acceleration. RocketWhisper leverages NVIDIA graphics cards with CUDA technology to drastically reduce transcription times. Compared to using only the CPU, processing speed can increase tenfold, which is critical for long-duration files.
• Real-time dictation with global hotkey. The program includes a continuous dictation mode that transcribes speech as the user speaks. Using a global hotkey combination, audio capture can be started or stopped from any application, inserting the text directly into the active field.
• Batch processing of audio and video. The tool allows uploading multiple audio or video files for sequential or parallel transcription. It is designed for journalists, researchers, and creators who need to convert large volumes of recordings into text.
• Export to SRT and VTT. Users can generate subtitle files in SRT (SubRip) and VTT (WebVTT) formats from any video or audio. This feature is aimed at creating accessible content for platforms like YouTube or Vimeo.
• Formatting with AI and LLMs. RocketWhisper integrates connectors with language models such as OpenAI, Claude, Gemini, and Groq. Once the transcription is obtained, it can be sent to these services to correct grammar, apply styles, or summarize the content, always under user control.
• Custom instructions for voice commands. The software supports spoken commands to modify text while dictating. For example, the user can say "new line" or "delete that" and the application executes the corresponding action without manual intervention.
• Automatic punctuation and correction. The engine incorporates automatic punctuation algorithms that insert commas, periods, and question marks based on detected intonation and pauses. It also features a contextual spell checker to improve the accuracy of the final text.
• Custom vocabulary and technical terms. Users can add specialized terms, proper nouns, or technical jargon to a local dictionary. This prevents transcription errors in fields such as medicine, law, or engineering.
• Application-specific modes. RocketWhisper adapts its behavior based on the active program. For example, it can apply different formatting rules when dictating into a word processor, an email client, or a command line.
• Voice search and application launcher. In addition to transcription, the program includes a command system for searching files on the computer or opening applications via voice commands. This functionality turns the tool into a local productivity assistant.
• Support for over ninety languages. Thanks to Whisper's multilingual foundation, RocketWhisper recognizes and transcribes a wide variety of languages, including dialects and regional variants, without needing to change settings manually.

The development of RocketWhisper began in 2023 by the Mojosoft team, with the goal of offering a private and efficient transcription solution. The application is primarily programmed in Python, using the Qt framework for the graphical interface and CUDA libraries for GPU acceleration. Since its initial release, it has received periodic updates that have expanded compatibility with Windows, macOS, and Linux operating systems.
