The present invention provides a voice wake-up method and a voice interaction device. The method includes the following steps that: voice input signals are received; the first similarity of the voice input signals and preset wake-up voice signals is determined according to a first acoustic model, and whether the first similarity exceeds a first preset threshold value is judged; and if the first similarity exceeds the first preset threshold value, second similarity between the speech input signals and the preset wake-up voice signals is determined according to a second acoustic model, and whether the second similarity exceeds a second preset threshold value is judged, if the second similarity exceeds the second preset threshold value, a voice interaction function is awaken, wherein the accuracy of the second acoustic model is higher than the accuracy of the first acoustic model. The voice wake-up method and the voice interaction device provided by the embodiment of the invention have the advantages of low power consumption and low wrong wake-up rate.

Voice wake-up method and voice interaction device

The invention discloses an information processing method and electronic equipment. The method comprises the following steps of acquiring an enable instruction, wherein the enabling instruction is usedfor instructing to call an eye protection function; and in response to the enabling instruction, enabling an eye protection function, the eye protection function comprising: if the display screen isin a turned-on state, determining whether to control the controllable light source to be turned on based on the ambient brightness value of the environment where the display screen is located, and ifthe ambient brightness value is lower than a preset brightness value, controlling the controllable light source to be turned on to change the ambient brightness of the environment where the controllable light source is located. When the enable instruction is activated, eye protection functions are called so that when the display screen is turned on, the display screen is turned off. The controllable light source can determine whether to be lightened or not according to the environment brightness value of the environment where the display screen is located, whether the controllable light sourceis lightened or not is controlled according to the environment brightness value, the problem that when the display screen is used when the environment brightness is too low and the display screen isin the lightened state, eye fatigue is caused by local highlight is avoided, and user experience is improved.

Information processing method and electronic equipment

The application provides a method and apparatus for speech recognition. The method comprises: with Chinese-character-based speech recognition, speech recognition is carried out on to-be-recognized named entity speech to identify a Chinese character sequence of a Chinese character recognition result of the to-be-recognized named entity speech; with Chinese-phonetic-alphabet-based speech recognition, speech recognition is carried out on the to-be-recognized named entity speech to identify a Chinese phonetic alphabet sequence of a Chinese phonetic alphabet identification result of the to-be-recognized named entity speech; according to the identified Chinese character sequence and the identified Chinese phonetic alphabet sequence, similarity degrees between all candidate named entities in a specific named entity list and the to-be-recognized named entity speech are determined; and on the basis of the similarity degrees between all candidate named entities in a specific named entity list and the to-be-recognized named entity speech, a speech recognition result of the to-be-recognized named entity speech is determined from the specific named entity list. Therefore, accuracy of identification of the named entity speech can be improved.

Method and apparatus for speech recognition

An interactive stringed instrument teaching system. The system is composed of an intelligent stringed instrument, a mobile terminal and a server. A Bluetooth module is mounted in both the intelligent stringed instrument and the mobile terminal. A microphone, a tuning module, a database, a teaching module and a game module are further arranged in the mobile terminal, wherein the teaching module and the game module comprise a performing module, a sound comparison module and a note determination module, and the teaching module and the game module are used for performing a current music score and using the sound comparison module to compare a collected sound with a standard sound, determining the accuracy of user performing, and guiding a user in a timely manner according to a determination result. A main control module, a sound wakeup module, an LED driving module and an LED matrix module are further mounted in the intelligent stringed instrument. According to the present invention, the learning difficulty and the threshold of a stringed instrument are reduced, and the interestingness of game learning is increased, and the system rapidly helps a primary user to truly enjoy the joy of music.

The invention discloses a method and a device for matching based on voice recognition. The method mainly includes determining character information, in an alphabetic form, converted from voice information; on the basis of a fuzzy matching strategy and according to alphabet, performing fuzzy matching to the converted character information of the character information stored in the alphabetic and Chinese character forms from a local database. As the single complete matching strategy applied in the prior art is expanded to the strategy of performing the fuzzy matching to the converted character information in the alphabetic form according to alphabet, voice recognition rate of the character information acquired by conversion is increased effectively, and further, the efficiency of the voice recognition technology is improved.

Method and device for matching based on voice recognition

The invention discloses a terminal awakening method The method comprises the following steps: in the terminal sleep state, power is only supplied to the DSP chip, and sound data of a sound to be judged is acquired by the DSP chip; feature extraction is performed on the sound data of the sound to be judged by the DSP chip to acquire a feature sequence of the sound to be judged; and the DSP chip is used to perform matching between the feature sequence of the sound to be judged and the feature sequence of a default target sound, and if the matching process is successful, then the AP of the terminal is activated The invention further correspondingly discloses a DSP chip and a terminal Through the terminal awakening method, the DSP chip and the terminal of the invention, the terminal can be awakened through a sound, and power is only supplied to the DSP in the terminal sleep state state, so advantages of less power consumption and high practicability can be realized

Terminal awakening method, DSP chip, and terminal

A voice recognition and matching method and device, and a computer program and a storage medium. The method mainly comprises: determining character information in pinyin form obtained after conversion from voice information (101); and according to a fuzzy matching policy, performing fuzzy matching, in character information in pinyin and Chinese character forms stored in a local database, on the character information obtained through conversion according to pinyin (102). A single total matching policy adopted in the prior is expanded to performing fuzzy matching on the character information in pinyin form obtained through conversion, which effectively increases the voice recognition rate of the character information obtained through conversion, thereby improving the efficiency of a voice recognition technology.
