The Speech Recognition Module is an AI offline speech recognition product designed to convert speech into actionable text or commands. The system utilizes a microphone to record human speech, which is then processed into specific digital signals for interpretation.
To ensure optimal performance , please note that speech recognition accuracy can be influenced by factors such as the speaker's accent, speech rate, and high levels of surrounding noise. We recommend utilizing this module in a relatively quiet environment.
V3.0 Features: The V3.0 version introduces voice self-learning functionality . This allows users to program one wake word and multiple command words, adapting to different languages and supporting personalized command sets.
