example 1

[0189] Figure 12 It is a flowchart of the voice recognition part 721 which concerns on this embodiment.

[0190] In Example 1, the starting point of the predetermined time is defined as the time of recognition (extraction) of the wake-up word.

[0191] The voice recognition unit 721 waits until a voice signal is input from the microphone 75 (NO in step S101 ). When a sound signal is input (Yes in step S101), try to textualize the sound of the input sound signal, and extract a wake-up word from the text of the sound (step S102). When extraction is possible (Yes in step S103), the elapsed time is reset, and measurement of the elapsed time is started (step S104). When the wake-up word cannot be extracted (No in step S103 ), it waits until the sound signal is input again.

[0192]When the voice recognition unit 721 continues to input a voice signal from the microphone 75 after extracting the wake-up word (YES in step S105), it recognizes the input voice signal as a user's inst...

example 2

[0195] In Example 1, let the elapsed time be the time elapsed after the voice recognition unit 721 extracted the wake-up word. However, further, the elapsed time after the voice recognition unit 721 extracts the control word may be used as the elapsed time. That is, in Example 2, the start point of the predetermined time is defined as the control word recognition (extraction) time. As a result, the user can instruct the lighting device X without uttering the wake-up word, as long as a predetermined time elapses after the user instructs the lighting device X (that is, until the elapsed time reaches the predetermined time).

[0196] Figure 13 A flowchart of the voice recognition unit 721 at this time is shown.

[0197] The voice recognition unit 721 performs the same processing as the above-mentioned steps S101 to S104. That is, when a sound signal is input, a wake-up word is extracted based on the sound signal, the elapsed time is reset, and measurement is started (steps S2...

example 3

[0215] The voice recognition circuit can also make the speaker output a third reminder sound different from the first reminder sound and the second reminder sound (for example, "beep beep" when the user's instruction is an indication that the lighting device X cannot be performed). the sound of).

[0216] For example, when an instruction to turn on the lighting device X that has already been turned on is given, and the light quantity or the color temperature has reached the upper limit (or lower limit) that can be adjusted, further raising (or lowering) them is performed. When instructing, etc., by outputting the third warning sound from the speaker, the user can be notified that the instruction is wrong, and the user can prevent the user from making such erroneous instructions many times.

[0217] Figure 15 A flowchart of the voice recognition unit 721 at this time is shown.

[0218] In addition, here, the lighting control unit 425 (refer to Figure 11 ) When the lighting...

Abstract

Provided is an illumination device that can prevent dust from accumulating on a sound collecting surface of a voice input body. This illumination device comprises a lighting control unit that, in accordance with a user's voice, controls lighting power which is supplied to a light source unit by a lighting power generation unit, wherein: a voice input body (75), to which the voice is inputted, is provided to a case (41) in a state where a sound collecting surface (751) is exposed from an opening of the case (41); and the sound collecting surface (751) is positioned further inward than the opening edge of the outer surface (471a) of the case (41).

Description

technical field [0001] The invention relates to a lighting device with sound recognition function. Background technique [0002] As a lighting device with a voice recognition function, for example, "a suspension-type lighting fixture has been proposed, which is characterized in that: a suspension base is provided on the ceiling surface; Electrically connected fixture main body, the suspended lifting lighting fixture is formed such that the horizontal projected area of ​​the fixture main body is larger than the horizontal projected area of ​​the suspension base, wherein a voice control unit equipped with a microphone and a voice recognition unit is provided on the suspension base The voice control unit recognizes the scheme of controlling the lighting and extinguishing of the main body of the appliance and the raising and lowering movement based on the command voice of the turning on and off of the human voice and the raising and lowering movement (for example, Patent Documen...
