The Gated Recurrent Units (GRU) model is a type of recurrent neural network (RNN) that is widely used for sequence modeling tasks, including speech recognition. It is an extension of the traditional RNN model with additional gating mechanisms to address the vanishing gradient problem and provide better long-term dependencies capturing capability.
In a GRU model, each recurrent unit has two gates: an update gate and a reset gate. The update gate determines how much of the previous hidden state should be passed on to the current step, while the reset gate decides how much past information should be ignored. These gates allow selective information flow and enable the model to store and update relevant information over long sequences of audio data.
Speech Recognition: GRUs are commonly used in speech recognition systems to convert audio input into transcriptions or commands. They excel in capturing phonetic and contextual information from spoken language.
Language Translation: The GRU model can be utilized to translate spoken language into text or to convert text from one language to another. It is effective at capturing language syntax and semantics over longer sequences.
Voice Command Recognition: GRUs are employed in voice command recognition systems, enabling devices to understand and respond to spoken instructions accurately. They excel at recognizing specific keywords or phrases within a continuous audio stream.
