Abstract

PURPOSE:To give output content surely to a worker by providing a voice synthesis processing section and a noise level measuring section so as to apply voice output with a level over a noise level even when a noise exists around the worker. CONSTITUTION:When a voice output control part 2 receives a coded voice output command 11 from a host system 1, required voice information is extracted from required voice information from a voice information storage part 3 and gives a command to a noise level measuring part 8 so as to measure the noise around the voice output device. The measuring part 8 transmits a measured value of a noise meter 9 to an output level converter 7. The converter 7 adds a predetermined constant to decide the output level, outputs a voice output level command 10 and a voice output adjusting part 5 sets a commanded voice output level. The information extracted from the voice information storage part 3 is fed to a voice synthesizer 4 and outputs a prescribed voice from a speaker 6 via the adjusting part 5 to which a prescribed output level is set.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an audio output device including a speech synthesis processing section and a noise level measuring section.

[Technical background of the invention and its problems] A voice output device in a voice response system that has a function of outputting voice has a problem in that it is difficult to recognize various instructions, notifications, and taps to the worker when outputting voice. Due to the noise level in the environment where the worker was located, the voice output command was output regardless of the presence or absence of a sufficient output level, so it was unclear whether the confirmation was sufficient or not, so the same voice was simply output. By simply repeating the output content several times, they were not necessarily concerned with whether or not the output content could be conveyed to the listener.

[Object of the Invention] It is an object of the present invention to solve the above-mentioned problems and to effectively use existing audio output devices.

[Summary of the Invention] The present invention includes a speech synthesis processing section and a noise level measurement section, and when outputting speech from the speech synthesis processing section according to a command from a host data processing device, the surrounding noise is measured and the noise level is adjusted to the level. In the audio output device configured to output audio from the speech synthesis processing unit by adjusting the generated output level accordingly, the audio output level is checked in accordance with instructions from the host data processing device to ensure that the listener is This is an audio output device characterized by being configured so that the content to be output can be conveyed to the user.

[Embodiments of the Invention] Next, embodiments of the present invention will be described. The drawing shows an audio output device consisting of the following components.

0) Control unit 2 that outputs audio information retrieval commands and IJ sound measurement commands in response to audio output commands 11 received from the host system (f) Audio information storage that outputs corresponding audio information in response to audio information retrieval commands from the control unit 2 Unit 3 (to a speech synthesizer 4 that synthesizes speech using the audio information output from the /9 sound audio information extractor 3) A sound level measurement unit that operates the sound level meter 9 in response to a noise measurement command from the control unit 2 and measures the noise. Part 8 (E) Output level converter 7 (E) Output level converter which inputs the noise measurement value from the noise level measurement part 8, corrects it with a predetermined setting value, and outputs the audio output level command 10. The volume of the synthesized voice synthesized by the voice synthesizer 4 is adjusted according to the voice output level command 10 from the voice synthesizer 7, and the voice output level 5 is outputted to the speaker 6. Output by following various steps.

(2) When the audio output device control unit 2 receives the audio output command 11 containing coded information sent from the host system 1, it simultaneously retrieves the necessary audio information from the audio information storage unit 3. An instruction is issued to the noise level measuring section 8 to measure the noise around the audio output device, which will be used as an index when performing the audio ratio No. 1.

(2) The noise level measuring section 8 transmits the measured value to the output level converter 7 using the sound level meter 9 according to instructions from the audio output section 112.

■) The output level converter 7 adds a predetermined value to the measured value to determine the corresponding audio output level, and gives an audio output level command of 1G to the audio output adjustment unit 5. According to this, the audio output adjustment section 5 sets the audio output level to the instructed audio output level.

θ) On the other hand, the information retrieved from the audio information storage unit 3 by the audio output command in the above @ item is sent to the audio synthesizer 4, and the audio output adjustment unit 5 whose output level was set in advance in item θ) is sent to the audio synthesizer 4. A predetermined sound is output from the speaker 6 to the outside via the speaker 6.

[Effect of the invention] According to the present invention, the following effects can be obtained.

In other words, even if there is noise around the worker, there is audio output at a level 1 [level above the noise level, so
Since the output content can be reliably communicated to the worker, work can be continued efficiently and the man-machine interface can be expected to improve.
