Title: Heating cooker
Inventor: TAKANO KUNIMASA
IPC: F24C15/00
Filed: 2017-10-25
Abstract: To provide a heating cooker capable of more surely recognizing an instruction for extinction by voice.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). In the cooking stove capable of executing such voice recognition processing, a threshold value in recognizing an instruction for extinction is determined to be lower than the threshold value in recognizing the voice instruction excluding the instruction for extinction. As the CPU can surely recognize the instruction for extinction of high emergency in comparison with the other voice instruction, it can cope with the emergency without any loss.SELECTED DRAWING: Figure 7
