Wake-up word recognition training system and method

A wake-up word recognition training system, comprising:

• a sentence database, storing a plurality of sentences and a phoneme sequence and a speech signal corresponding to each of the sentences;
• a phoneme disassembly module, disassembling a wake-up word inputted from the outside to obtain a wake-up word phoneme sequence;
• a phoneme analysis module, matching the wake-up word phoneme sequence to the sentences and/or phoneme sequences thereof, to obtain wake-up word part-of-speech sentences and non-wake-up word part-of-speech sentences;
• and
• a wake-up word recognition module, constructing a deep neural network model according to a phoneme combination of the wake-up word part-of-speech sentences and the non-wake-up word part-of-speech sentences, and training the deep neural network model according to phoneme sequences and speech signals of the wake-up word part-of-speech sentences and the non-wake-up word part-of-speech sentences, to establish a wake-up word recognition model;
• wherein the wake-up word recognition training system includes an input module, a sentence database, and a processing module, where the processing module includes a phoneme disassembly module, a phoneme comparison module, a sentence classification module, a wake-up word recognition module and a generic speech recognition module;
• and
• wherein text input or at least one of a speech input device and a microphone is used to input a personalized wake-up word to obtain the wake-up word.
