The microphone may be a microphone provided for speech recognition control, or may share a telephone function of a hands-free function. The microphone may also be a microphone of the user's cell phone.

When using the microphone of the mobile phone, the mobile phone and the massage chair can be used while being connected to each other through the short distance communication such as Bluetooth.

The voice recognition processor of the massage chair receives the electrical signal converted by the microphone through the middleware, performs speech recognition on the converted electrical signal, and extracts text data as voice command information as a result of speech recognition. The text data extracted by the speech recognition processing unit is transmitted to the middleware before being transmitted to the control unit.

The middleware determines whether the text data received from the voice recognition processor of the massage chair is a reserved word for voice recognition control of a massage chair or a reserved word for voice recognition control of a mobile phone.

The middleware transmits the text data to the control unit of the massage chair so that the text data controls the voice recognition of the massage chair. Alternatively, if the text data is not a reserved word for speech recognition control of the massage chair, the text data is transmitted to the mobile phone so that the voice recognition control of the mobile phone is performed. That is, the middleware automatically determines whether the voice signal generated by the user utterance is a reserved word for voice recognition control of the massage chair or a reserved word for voice recognition control of the mobile phone, and distributes it.

The command output interface is for transmitting a control command signal corresponding to voice command information extracted as a result of speech recognition from the control unit to the control target device.

 The input unit may be a touch screen implemented on at least one or more buttons or a display provided on the massage chair. Such a massage chair may be provided directly on the massage chair, or may be implemented through a remote controller. Such an input unit may be applied to a massage chair by adopting a known technique.

The user can select one of the complex functions of the massage chair through the operation of the input unit, and can include various settings from the selected function. The voice recognition button provided on the support unit may be included in at least one button constituting the input unit.

The control unit can perform the necessary control by engaging with other massage units in front of the massage unit of the seat plate, the backrest, and the calf receiving unit. For example, an initial entry screen is displayed by driving a processor related to a voice recognition function with respect to operation of a voice recognition button, or an associated voice guidance message is outputted through a speaker. In addition, the control unit receives the voice command information provided from the voice recognition processing unit, and performs control corresponding to the voice command information.

The memory may store an application or a program executed to perform a voice recognition function of a massage chair, screen display data necessary for executing the program, voice data, sound effect data, and the like.

For example, a guide screen for each function, a message, a video data, an error content, and the like are output through the display. Such a display may be provided directly on the massage chair itself or on a remote controller.

The speaker outputs the voice needed when the complex function such as the voice recognition function is performed in addition to the hands-free function of the massage chair. For example, voice data stored in a memory, effect sound data, and announcements for each function may be outputted through a speaker.

In order to implement a massage chair according to an embodiment of the present invention, the middleware includes a voice input / output unit and a voice recognition gateway.

The voice input / output unit activates the microphone in a state where voice input is possible in response to the operation of the voice recognition button. When the user speaks while the microphone is activated and the voice signal is inputted through the microphone, the voice input / output unit transmits the inputted voice signal to the voice recognition processor of the massage chair.

The voice signal thus transmitted is converted into text data by the voice recognition processor of the massage chair and then transmitted to the voice recognition gateway of the middleware.

The voice recognition gateway determines whether the text data received from the voice recognition processor of the massage chair is a reserved word for speech recognition control of a massage chair or a reserved word for voice recognition control of a mobile phone. The middleware transmits the text data to the control unit of the massage chair when the text data is a reserved word for voice recognition control of the massage chair so that the voice recognition control of the massage chair is performed. Alternatively, if the text data is not a reserved word for voice recognition control of the massage chair, text data is transmitted to the mobile phone so that voice recognition control of the mobile phone is performed.

The process of determining whether the text data is a reserved word for voice recognition control of a massage chair or a reserved word for voice recognition control of a mobile phone is performed by referring to comparison reference information provided in the voice recognition gateway in the voice recognition gateway. For example, voice recognition gateways have text pattern matching logic and intent analysis logic.

The text pattern matching logic compares the text data input from the voice recognition processor of the massage chair with the text data pattern matching to determine whether the text data inputted to the voice recognition gateway is a reserved word for voice recognition control of the massage chair or voice recognition control of the mobile terminal .

The intention analysis logic distinguishes between the reserved words of the massage chair and the reserved words of the mobile phone by referring to the inherent characteristics of the reserved words for the massage recognition control of the massage chair and the unique characteristics of the reserved words for the voice recognition control of the mobile phone. For example, the signal waveform can be used to distinguish the question type from the imperative type. The short / imperative type judges a reserved word for voice recognition control of massage chair and the long word / question type can be used as a reserved word for voice recognition control of a mobile phone.

This is mainly due to the word-oriented command form in the case of reserved words for voice recognition control of massage chair and in the case of the reserved word for voice recognition control of the mobile phone in the form of sentence-oriented query response form. In the case of a question, it is judged the question type through the form that the end part of the sentence is higher than the other part, and the imperative type can judge the general imperative type by the sound of the end part not rising.

In addition to the pattern matching and the intention analysis, other judgment criteria can be applied to discriminate whether the massage is a reserved word for voice recognition control of a massage chair or a reserved word for voice recognition control of a mobile phone.

The speech recognition processing section includes an analog-to-digital conversion section, a speech recognition section, a speech detection section, a word recognition section, and a word standard pattern database.

The voice signal converted into the electrical signal output from the microphone is in analog form. For speech recognition, this analog type electrical signal must be converted into a digital type electrical signal. The analog-to-digital conversion unit converts an analog type electrical signal input from a microphone into a digital type electrical signal.

The voice analysis unit analyzes the voice signal converted into the digital type electrical signal and extracts the feature pattern. The voice analysis unit divides the voice signal converted into the electric signal into frames of a preset size, and extracts the feature patterns for each frame. The extraction of the feature pattern in the speech analysis unit is performed by analyzing information such as frequency or amplitude of the speech signal.

The voice detection unit detects a section in which the voice exists in the voice signal converted into the digital type electrical signal.

At this time, noise may be generated around the massage chair. In the present invention, in order to provide accurate and high voice recognition rate among such noises, the massage chair detects the beginning and end of the section in which the voice of the voice signal exists It is important.

The word recognizer selects the word most similar to the voice signal input through the microphone. In the word standard pattern database, a plurality of reserved words, for example, first, second, mode, reservation, phone, etc., are stored as a standard pattern. The word recognizer compares the feature pattern acquired through the analysis of the speech signal with the standard pattern prepared in advance and selects a standard pattern most similar to the feature pattern. The word recognition section provides the information of the reserved words corresponding to the selected standard pattern to the control section as the recognition result.
