Abstract
A vocal feedback device comprising: a microphone; a fundamental frequency accentuator electrically connected to the microphone, a delay circuit electrically connected to the fundamental frequency accentuator, and a speaker electrically connected to the delay circuit. The device configured to convert vocal utterances received at the microphone into an electrical signal, impose a time delay before transmitting the electrical signal, after the time delay, transmit the electrical signal to the speaker, and convert the electrical signal to an audio signal using the speaker, the audio signal being a replication of the vocal utterances.
Claims20
A vocal feedback device to train a user's voice for improved tonal qualities of speech, comprising:
- a microphone coupled to a delay circuit;
- a fundamental frequency accentuator coupled to a speaker;
- the delay circuit coupled to the fundamental frequency accentuator, where the delay circuit is configured to impose a time delay before transmitting an electrical signal received from the microphone, and where the fundamental frequency accentuator is configured to modify the electric signal before transmitting a modified electrical signal;
- and
- where the speaker is configured to convert the modified electrical signal to an audio signal to be heard by the user.
A vocal feedback device to assist the speech of a user, comprising:
- a directional microphone pointed at the user and in receipt of input sound waves generated from the speech of the user;
- an electrical signal produced from the input sound waves and generated by the microphone;
- a delay circuit coupled to the microphone;
- a fundamental frequency accentuator coupled to the delay circuit;
- a modified electrical signal generated by the fundamental frequency accentuator where a fundamental frequency of the input sound waves is accentuated in the modified electrical signal;
- a directional speaker coupled to the fundamental frequency accentuator and pointed at the user;
- and
- a time delay introduced to the electrical signal before the modified electrical signal is converted to output sound waves by the speaker.
A method for improving a vocalization of a user, comprising:
- positioning a vocal feedback device comprising a microphone coupled to a delay circuit and a fundamental frequency accentuator coupled to the delay circuit and to a speaker;
- generating an electrical signal with the microphone from the vocalization;
- imposing a delay with the delay circuit on the electrical signal;
- generating a modified electrical signal with the fundamental frequency accentuator from the electrical signal;
- and
- transmitting sound waves with the speaker generated from the modified electrical signal.
