Discovering Good Linux Software for Voice Assistance

Recently, I discovered the VOSK-API, an open-source library with high-quality speech-to-text capabilities. However, I couldn't find any front-ends specifically for Linux, so I developed a utility for integrating it into applications like typing in document.

Evaluating Voice Assistants in the Linux Ecosystem

The group I converse with frequently usually highlights just two prominent voice recognition systems: and Wave2Letter. Personally, I have neither used these systems nor rely on speech recognition anymore. Therefore, my assessment is primarily based on the feedback and reviews from other users.

Different Dimensions of Speech Technology in Linux

Speech technology encompasses multiple dimensions:

Speech enabled accessibility software for individuals with disabilities. Bundled AI systems for desktop users, integrating speech recognition, text-to-speech, natural language processing, and more.

Let's delve into the popular speech synthesis and speech recognition systems available for Linux.

Popular Speech Synthesis Systems for Linux

The most popular speech synthesis application for Linux is the Festival Speech Synthesis System. It offers high-quality text-to-speech, making it a reliable choice for accessibility and general speech output on Linux.

Popular Speech Recognition Systems for Linux

For speech recognition, CMU Sphinx stands out. It is well-maintained and has a wide range of trained models available online. Additionally, the latest version of Sphinx 4 in Java performs quite well.

Exploring Voice Control Utilities

Here are some voice control utilities that can enhance your Linux experience:

CVoiceControl: A configuration utility for the microphone and a vocabulary editor for adding commands to the speech recognition system. OpenMindSpeech: Another utility designed for voice control. Ears: A comprehensive tool for integrating voice features into your applications. NICO ANN Toolkit: A toolkit for creating and managing artificial neural networks, useful for voice recognition tasks.

While there are several options available, it is important to note that there is no polished speech recognition software tailored for Linux that matches the robustness of Dragon NaturallySpeaking, Windows Speech Recognition, or the new Mac speech recognition.

Challenges and Alternative Solutions

Some older speech recognition systems, like the Linux version of ViaVoice, have been integrated into Xvoice but are no longer supported due to lack of development and compatibility issues with current Linux versions. This leaves developers and users with limited options.

Your best shot at achieving speech recognition on Linux is to utilize a Windows-based speech recognition system within a virtual environment. Some people have successfully used tools like Dragon NaturallySpeaking under Wine.
