Method of processing telephone signals and electronic device thereof
A method of processing telephone sound is disclosed. Before the telephone sound is transmitted, the frequencies of high frequency consonants are lowered. If the recipient has severe hearing impairment, the frequencies of the high frequency consonants are lowered again.
1. A method of processing telephone sounds for a user using a phone, the method comprising:
in a case of transmitting the telephone sounds from the phone:
receiving a sound transmission segment from a signal of a sound input into a microphone module of the phone; and
determining whether the sound transmission segment has high frequency consonants using an audio processing module of the phone;
wherein if the sound transmission segment has the high frequency consonants, compressing and/or shifting the frequency of the sound transmission segment and then transmitting the sound transmission segment to another phone; and
if the sound transmission segment does not have the high frequency consonants, then transmitting the sound transmission segment directly to another phone.
2. The method of processing telephone sound as claimed in claim 1 , wherein the method further comprises:
in a case of receiving a sound input from another phone:
receiving a sound-receiving segment from a signal of the sound input from the other phone; and
determining whether the sound-receiving segment has high frequency consonants;
wherein if the sound-receiving segment has the high frequency consonants, lowering the frequency of the sound-receiving segment and then outputting the sound-receiving segment; and
if the sound-receiving segment does not have the high frequency consonants, then outputting the sound-receiving segment directly.
3. The method of processing telephone sound as claimed in claim 2 , wherein the frequency of the sound-receiving segment is lowered based on an adjustable parameter that reflects the hearing status of the user.
4. The method of processing telephone sound as claimed in claim 3 , wherein the frequency of the sound-receiving segment is lowered based on a telephone bandwidth.
5. The method of processing telephone sound as claimed in claim 4 , wherein a sound segment is determined to have high frequency consonants if the sound transmission segment has the following characteristics:
the energy of the sound transmission segment below 1,000 Hz is less than 50% of all of the energy of the sound transmission segment; and
the energy of the sound transmission segment above 2,000 Hz is greater than 30% of all of the energy of the sound transmission segment.
6. The method of processing telephone sound as claimed in claim 5 , wherein a sound segment is determined to have high frequency consonants if the sound-receiving segment has the following characteristics:
the energy of the sound transmission segment below 1,000 Hz is less than 50% of all of the energy of the sound transmission segment; and
the energy of the sound transmission segment above 2,000 Hz is greater than 30% of all of the energy of the sound transmission segment.
7. The method of processing telephone sound as claimed in claim 1 , wherein a sound segment is determined to have high frequency consonants if the sound transmission segment has the following characteristics:
the energy of the sound transmission segment below 1,000 Hz is less than 50% of all of the energy of the sound transmission segment; and
the energy of the sound transmission segment above 2,000 Hz is greater than 30% of all of the energy of the sound transmission segment.
8. An electronic device, comprising a processor, a memory, a microphone module, and a broadcast module, wherein the memory, the microphone module, and the broadcast module are electrically connected to the processor, and the memory comprises a software program, and the processor operative with the software program to perform the steps of:
in a case of receiving the sound from another phone;
receiving a sound-receiving segment from a signal of a sound input from another phone; and
determining whether the sound-receiving segment has high frequency consonants;
wherein if the sound-receiving segment has the high frequency consonants, compressing and/or shifting the frequency of the sound-receiving segment and then outputting the sound-receiving segment; and
if the sound-receiving segment does not have the high frequency consonants, outputting the sound-receiving segment directly,
in which the processor is further operative with the software program to perform the step of:
in a case of transmitting the sound:
receiving a sound transmission segment from a signal of a sound input into the phone; and
determining whether the sound transmission segment has high frequency consonants;
wherein if the sound transmission segment has the high frequency consonants, lowering the frequency of the sound transmission segment and then outputting the sound transmission segment; and
if the sound transmission segment does not have the high frequency consonants, outputting the sound transmission segment directly.
9. The electronic device as claimed in claim 8 , wherein the frequency of the sound-receiving segment is lowered based on an adjustable parameter that reflects the hearing status of the user.
10. The electronic device as claimed in claim 9 , wherein the frequency of the sound-receiving segment is lowered based on a telephone bandwidth.
11. The electronic device as claimed in claim 10 , wherein a sound segment is determined to have high frequency consonants if the sound-receiving segment has the following characteristics:
the energy of the sound transmission segment below 1,000 Hz is less than 50% of all of the energy of the sound transmission segment; and
the energy of the sound transmission segment above 2,000 Hz is greater than 30% of all of the energy of the sound transmission segment.
12. The electronic device as claimed in claim 11 , wherein a sound segment is determined to have high frequency consonants if the sound transmission segment has the following characteristics:
the energy of the sound transmission segment below 1,000 Hz is less than 50% of all of the energy of the sound transmission segment; and
the energy of the sound transmission segment above 2,000 Hz is greater than 30% of all of the energy of the sound transmission segment.
13. The electronic device as claimed in claim 8 , wherein a sound segment is determined to have high frequency consonants if the sound transmission segment has the following characteristics:
the energy of the sound transmission segment below 1,000 Hz is less than 50% of all of the energy of the sound transmission segment; and
the energy of the sound transmission segment above 2,000 Hz is greater than 30% of all of the energy of the sound transmission segment.
14. A method of processing telephone sounds for a user using a phone, the method comprising:
in a case of transmitting the telephone sounds from the phone:
receiving a sound transmission segment from a signal of a sound input into a microphone module of the phone; and
determining whether the sound transmission segment has high frequency consonants using an audio processing module of the phone;
wherein if the sound transmission segment has the high frequency consonants, compressing the frequency of the sound transmission segment and then transmitting the sound transmission segment to another phone; and
if the sound transmission segment does not have the high frequency consonants, then transmitting the sound transmission segment directly to another phone.
