A method for training vibrotactile speech perception in the absence of auditory speech includes selecting a first word, generating a first control signal configured to cause at least one vibrotactile transducer to vibrate against a person's body with a first vibration pattern based on the first word, sampling a second word spoken by the person, generating a second control signal configured to cause at least one vibrotactile transducer to vibrate against the person's body with a second vibration pattern based on the sampled second word, and presenting a comparison between the first word and the second word to the person. An array of vibrotactile transducers can be in contact with the person's body. A method for improving auditory and/or visual speech perception in adverse listening conditions or for hearing-impaired individuals can also include sampling a speech signal, extracting a speech envelope, and generating a control signal configured to cause a vibrotactile transducer to vibrate again a person's body with an intensity that varies over time based on the speech envelope.

A method of providing a haptic signal is described therein, the method comprising the steps of providing a first source signal, filtering a mid-range band of the first source signal for restricting a bandwidth of the first source signal to the mid-range band, integrating the filtered mid-range band of the first source signal to identify an amplitude of the filtered first source signal, providing a voltage control amplifier with a proportional calibrated voltage on a basis of the integration of the filtered first source signal for adjusting an amplitude of the filtered source signal, isolating a trans-conductance voltage control amplifier high impedance output from a second source signal with a buffer, filtering the filtered source signal with a low pass filter to identify original sub-frequencies of an audio program and combining the identified original sub frequencies of the audio program with transposed midrange frequencies in a haptic signal.

A process for interfacing with an electronic communications device including a single input interface (SII) for accessing an electronic digital assistant and voice control includes detecting a first activation of the SII, and responsively playing back a first audio feedback indicative of activation of a voice input function. Then monitoring for one of two or more pre-configured voice control keywords, a first associated with a local electronic communications device function and a second associated with initiating a particular infrastructure-based electronic digital assistant function. When the first, playing back a second audio feedback indicative of acknowledgement of a local device function, and performing the local device function; when the second, playing back, a third audio feedback indicative of acknowledgement of a infrastructure-based electronic digital assistant function, and performing the infrastructure-based electronic digital assistant function.

A desired effect can be exerted on the mental and physical state of a listener of a piece of music with a vibration based on the piece of music even when the piece of music has almost no relaxation or awakening effect. As a vibration signal for vibrating a vibration generation device while the piece of music is being played, the audio signal in the band corresponding to the mode is extracted from the audio signal of the music, and a vibration signal is generated based on the extracted audio signal.

A wearable auditory feedback device includes a frame, a plurality of microphone arrays, a plurality of feedback motors, and a processor. The frame is wearable on a user's head or neck. The microphone arrays are embedded in the frame on a left side, a right side, and a rear side with respect to the user. The feedback motors are also embedded in the frame on the left side, the right side, and the rear side with respect to the user. The processor is configured to receive a plurality of sound waves collected with the microphone arrays from a sound wave source, determine an originating direction of the sound waves, and activate a feedback motor on a side the frame corresponding to the originating direction.

A speech remote control device includes a speech input unit, a speech identification unit, a motion setting unit, a transmit unit and a receiving unit. The speech input unit converts a received speech command into a speech signal. The speech identification unit receives the speech signal, and transmits an encoded message. The motion setting unit receives and decodes the encoded message to generate a combination message with a proceeding control command and a turning control command, or comprising a series of sub-combination messages. The transmitting unit receives and transmits the combination message to the receiving unit provided on the remote control car. The remote control car is driven by the receiving unit to automatically change direction or make more than one turn during proceeding. Thus, only one speech command controls the remote control car to simultaneously proceed and make a turn without sending any additional command for changing direction.
