<prompt> Hlwaya diphephetso tse pedi ho aheng mokgwa wa temoho ya puonan  <response>: Instruction in English: Identify two challenges in building a speech recognition system . Response in English: There are several challenges in building a speech recognition system, but two of the most common are:1. Accents and variations in speech patterns: Accents and variations in speech can make it difficult for speech recognition systems to accurately understand what users are saying. Speech patterns vary greatly not only between individuals, but also between regions, languages, and dialects, and accounting for the multitude of variations is a complex task.2. Background noise: A speech recognition system must be able to filter out background noise and distinguish between it and the users voice. This can be very challenging, especially when the system is used in environments with high levels of ambient noise, such as busy public spaces, or when the user is speaking in a low voice. The system must be able to distinguish between the users voice and other sounds in order to accurately transcribe their speech. .
