Remote or server-based SR – transmits an audio speech file to a remote server to convert the file into a text string file.This is becoming critical for protecting intellectual property (IP) and avoiding unwanted surveillance (2018). This refers to self-contained systems in which all aspects of SR are performed entirely within the user's computer. Discrete speech recognition (DSR) – processes information on a local machine entirely.The user has two main processing options: The first step is to begin recording an audio stream on a computer.

VoxForge is a free speech corpus and acoustic model repository that was built to collect transcribed speech to be used in speech recognition projects.
It is essential to compile a speech corpus to produce acoustic models for speech recognition projects. As a result, several projects dedicated to creating Linux speech recognition programs were begun, such as Mycroft, which is similar to Microsoft Cortana, but open-source. In the early 2000s, there was a push to get a high-quality Linux native speech recognition engine developed.
In 2002, the free software development kit (SDK) was removed by the developer. In the late 1990s, a Linux version of ViaVoice, created by IBM, was made available to users for no charge. 3 Running Windows speech recognition software with Linux.1.3.3 Proprietary speech recognition engines.
