Title:
HEATING COOKER
Document Type and Number:
Japanese Patent JP2019078462
Kind Code:
A
Abstract:
To provide a heating cooker capable of reducing user's stress caused by that voice instruction is not recognized though it is repeatedly input.SOLUTION: A CPU of a cooking stove converts a voice instruction input from the external into waveform data (S42). The CPU calculates coincidence rate of the converted waveform data and an acoustic model data stored in a non-volatile memory (S44). When the coincidence rate is over a threshold value (S48:YES), recognition of the voice instruction is determined (S49). When the coincidence rate is the threshold value or less (S48:NO), recognition failure of the voice instruction is determined (S54). The CPU counts the number of times of recognition failures k (S56). In a case when the voice instruction is repeatedly input regardless of the recognition failure, a risk of noise is low. When the number of times of recognition failures k is three times or more (S46:YES), the CPU reduces the threshold value (S47). Thus a state that the voice instruction from a user can be easily recognized, can be provided.SELECTED DRAWING: Figure 7
