  8. The speech control device according to any one of claims 1 to 7, wherein the execution unit causes the way of speaking the second utterance to differ from the way of speaking the first utterance based on the way of speaking the first response.
  9. The speech control device according to any one of claims 1 to 8, wherein the execution unit causes the dialect used in the second utterance to differ from the dialect used in the first utterance based on the dialect used in the first response.
  10. The system includes an execution unit that, when a condition is met, causes an electrical device to execute a first utterance, and the next time the condition is met, causes the electrical device to execute a second utterance that is different from the first utterance based on whether or not a first response was input to the electrical device in response to the first utterance, or the characteristics of the first response. The execution unit, if it is confirmed for a second number of consecutive times that there is no second response input to the electrical device in response to the second utterance, or that the content of the second response requests that the utterance not be executed, then stops the electrical device from executing the second utterance. The execution unit, if the absence of the first response or the content of the first response requesting that the utterance not be executed is repeated a first number of times in a row, stops causing the electrical device to execute the first utterance. The second number of times is greater than the first number of times for the speech control device.
  11. A speech control device according to any one of claims 1 to 10, The aforementioned electrical equipment, A speech system equipped with the following features.

Description

This disclosure relates to a speech control device and a speech system. Patent Document 1 discloses an e-book playback device. This e-book playback device can select a speech synthesis database to be used according to specified information input by the user, thereby allowing playback with different voice qualities for each character, or with a voice quality preferred by the user. (Paragraphs 0020 and 0027). Japanese Patent Publication No. 2005-321706 This is a block diagram of the air purifier according to the first embodiment.This figure illustrates the modification of speech performed by the air purifier of the first embodiment.This flowchart shows the processing flow performed by the air purifier of the first embodiment.This flowchart shows the processing flow performed by the air purifier of the first embodiment. The embodiments of this disclosure will be described below with reference to the drawings. In the drawings, identical or equivalent elements are denoted by the same reference numerals, and redundant descriptions are omitted. 1. First Embodiment 1.1 Air Purifier Figure 1 is a block diagram of the air purifier according to the first embodiment. The air purifier 1 of the first embodiment, as illustrated in Figure 1, purifies the surrounding air. The air purifier 1 may perform operations other than purifying the surrounding air. For example, the air purifier 1 may perform operations such as cooling, heating, dehumidification, humidification, and ion supply. Furthermore, the air purifier 1 executes a speech utterance 11 in conjunction with the occurrence of a speech trigger, and, based on the user's response 12 input to the air purifier 1 in response to the executed speech utterance 11, controls the speech utterance 11 to be executed in conjunction with the next occurrence of a speech trigger. As shown in Figure 1, the air purifier 1 comprises an air purification unit 31, a human presence sensor 32, an illuminance sensor 33, an operation unit 34, a speaker 35, a microphone 36, and a speech control device 37. The air purification unit 31 draws in air from outside the air purifier 1, purifies the inhaled air, and blows the purified air out to the outside of the air purifier 1. The air purification unit 31 includes a fan, a filter, etc. The fan generates an airflow that travels from outside the air purifier 1, through the filter, to the outside of the air purifier 1. The filter allows the air flowing through the generated airflow to pass through, removing substances contained in the air. These substances include odor components, dust, pollen, PM2.5, etc. The motion sensor 32 detects whether or not a person is present around the air purifier 1 and outputs a detection result 41 indicating whether or not a person is present around the air purifier 1. The illuminance sensor 33 detects the illuminance around the air purifier 1 and outputs a detection result 42 indicating the illuminance around the air purifier 1. The operation unit 34 detects operations performed on it and outputs a detection result 43 indicating the operations performed on it. The operation unit 34 can be a button, dial, slider, touch panel, touchpad, etc. The speaker 35 emits sound corresponding to the input audio signal 44. The microphone 36 outputs an audio signal 45 corresponding to the input audio. The speech control device 37 inputs an audio signal 44 to the speaker 35, causing the speaker 35 to emit sound. This causes the speech control device 37 to instruct the air purifier 1 to perform the speech 11. The speech control device 37 identifies the voice input to the air purifier 1 based on the voice signal 45 output by the microphone 36. After the air purifier 1 has performed the speech 11, the speech control device 37 identifies the user's response 12, which is the voice input to the air purifier 1. Furthermore, the speech control device 37 controls the timing for the air purifier 1 to execute the speech 11 based on the detection result 41 output by the human presence sensor 32, the detection result 42 output by the illuminance sensor 33, and the detection result 43 output by the operation unit 34. Furthermore, the speech control device 37 controls the next speech 11 to be executed by the air purifier 1 based on the user's response 12 input to the air purifier 1 after the air purifier 1 has executed the speech 11. The speech control device 37 and the air purifier 1 constitute a speech system that controls the speech utterances 11. The speech control device 37 is built into the air purifier 1. The speech control device 37 may also be built into a device that communicates with the air purifier 1. For example, the speech control device 37 may be built into a cloud server that communicates with the air purifier 1. The speech control device 37 may also control the speech utterances 11 to be executed by electrical devices other than the air purifier 1. For example, the speech control device 37 may control the speech utterances 11 to be exe
