Abstract

An apparatus for adjusting a prompt voice depending on an environment comprises a receiver module used for receiving a background sound, an analyzer module generating a control signal according to the background sound and an output module adjusting an output frequency of a prompt voice through the control signal and outputting the adjusted prompt voice.

Claims

1. An apparatus for adjusting a prompt voice depending on an environment, comprising:

a receiver module, used for receiving a background sound;

an analyzer module, generating a control signal according to the background sound; and

an output module, adjusting an output frequency of a prompt voice through the control signal and outputting the adjusted prompt voice.

2. The apparatus for adjusting a prompt voice depending on an environment according to claim 1, wherein the analyzer module analyzes the background sound to generate a background frequency range corresponding to the background sound.

3. The apparatus for adjusting a prompt voice depending on an environment according to claim 2, wherein the output module adjusts a frequency range of the prompt voice not to overlay the background frequency range.

4. The apparatus for adjusting a prompt voice depending on an environment according to claim 1, wherein the analyzer module compares a volume of the background sound with at least one average volume to generate the control signal.

5. The apparatus for adjusting a prompt voice depending on an environment according to claim 4, wherein if the control signal received by the analyzer module is that the volume of the background sound is higher than the average volume, the output module adjusts the output frequency of the prompt voice higher.

6. The apparatus for adjusting a prompt voice depending on an environment according to claim 4, wherein if the control signal received by the analyzer module is that the volume of the background sound is lower than the average volume, the output module adjusts the output frequency of the prompt voice lower.

7. The apparatus for adjusting a prompt voice depending on an environment according to claim 4, further comprising:

a setting module, allowing a user to set the average volume.

8. The apparatus for adjusting a prompt voice depending on an environment according to claim 1, further comprising:

a voice frequency data base, used for storing the prompt voice consisting of multiple different frequencies.

9. The apparatus for adjusting a prompt voice depending on an environment according to claim 8, wherein the output module captures the prompt voices with one of the different frequencies from the voice data base according to the control signal.

10. The apparatus for adjusting a prompt voice depending on an environment according to claim 8, wherein the voice frequency data base is set by a user himself.

11. The apparatus for adjusting a prompt voice depending on an environment according to claim 1, further comprising:

an alarm module, emitting a warning signal if the volume of the background sound is larger than a warning volume.

12. A method for adjusting a prompt voice depending on an environment, comprising the following steps:

(a) receiving a background sound;

(b) generating a control signal according to the background sound;

(c) adjusting an output frequency of a prompt voice through the control signal;

(d) outputting the adjusted prompt voice.

13. The method for adjusting a prompt voice depending on an environment according to claim 12, wherein Step (a) further comprises:

analyzing the background sound to generate a background frequency range corresponding to the background sound.

14. The method for adjusting a prompt voice depending on an environment according to claim 13, wherein Step (c) further comprises:

adjusting a frequency range of the prompt voice not to overlay the background frequency range.

15. The method for adjusting a prompt voice depending on an environment according to claim 12, wherein Step (b) further comprises:

comparing a volume of the background sound with at least one average volume and generating the control signal.

16. The method for adjusting a prompt voice depending on an environment according to claim 15, wherein if the volume of the background is higher than the average volume, the output frequency of the prompt voice is adjusted higher.

17. The method for adjusting a prompt voice depending on an environment according to claim 15, wherein if the volume of the background is lower than the average volume, the output frequency of the prompt voice is adjusted lower.

18. The method for adjusting a prompt voice depending on an environment according to claim 15, further comprising:

allowing a user to set the average volume.

19. The method for adjusting a prompt voice depending on an environment according to claim 12, further comprising:

storing the prompt voice consisting of multiple different frequencies; and

capturing the prompt voice with one of the different frequencies to be the adjusted prompt voice according to the control signal.

20. The method for adjusting a prompt voice depending on an environment according to claim 19, wherein the prompt voice consisting of the multiple difference frequencies is set by a user himself.

21. The method for adjusting a prompt voice depending on an environment according to claim 12, further comprising:

emitting a warning signal if a volume of the background sound is larger than a warning volume.
