According to some embodiments of the present disclosure, smart TV voice processing systems and methods are provided.  FIG. 1  is a flow diagram of the voice processing process for smart TVs according to some embodiments of the present disclosure; as shown in  FIG. 1 , the process comprises at least the following steps: 
         [0045]    In step S 102 , a smart TV initiates a wireless voice channel. 
         [0046]    In some embodiments of the present disclosure, a smart TV refers to a terminal, equipped with an operating system, wherein software programs can be freely installed and uninstalled, and includes functions such as video-playing, entertainment, gaming, and the like; and the smart TV has a network connectivity through a cable or a wireless network card. 
         [0047]    In some embodiments of the present disclosure, the smart TV initiates the wireless voice channel between the smart TV and a mobile terminal, wherein the mobile terminal can be a smart phone, a tablet PC (PAD), a PDA or other known or to be known smart terminal devices, as discussed above. The smart TV and the mobile terminal each has a wireless communication module, and the smart TV and the mobile terminal can realize a wireless communication connection through their respective wireless communication module, so as to establish the wireless voice channel between the smart TV and the mobile terminal, wherein the wireless communication module may be, for example, but is not limited to, a WIFI® module, a Bluetooth® module or a wireless USB® module, and the like; however, the present disclosure is not so limited and can include any other type of wireless communication module. 
         [0048]    In step S 104 , the smart TV receives voice signals through the voice channel. 
         [0049]    When the smart TV initiates the wireless voice channel between the smart TV and the mobile terminal, the smart TV receives the voice signals from the mobile terminal through the established voice channel. Prior to this step, the mobile terminal needs to acquire the voice signals in advance. A detailed account of how the mobile terminal acquires the voice signals is provided below. 
         [0050]    In some embodiments of the present disclosure, the user inputs a voice signal through a microphone of the mobile terminal, the mobile terminal performs an analog-to-digital conversion and other processes after the microphone acquires an analog voice signal, and then a digital voice signal is transmitted to the smart TV through the voice channel. In this case, the mobile terminal achieves a virtual microphone function of the smart TV, and the mobile terminal can be regarded as the voice input device for the smart TV. 
         [0051]    In some embodiments of the present disclosure, the mobile terminal stores a plurality of voice signals received in advance in other manners, or recorded in advance, and the user selects the desired voice signals from the plurality of stored voice signals and transmits the voice signals to the smart TV. 
         [0052]    In step S 106 , the smart TV determines a current application scenario and correspondingly processes the voice signals according to the current application scenario. 
         [0053]    In the present disclosure, the smart TV has a variety of application scenarios, for example, including, but not limited to, a video application scenario, an entertainment application scenario and other known or to be known application scenario of a smart TV. Furthermore, the video application scenario comprises, for example, basic cable and wireless TV functions, network TV, DVD video player, and other known or to be known scenarios; the entertainment application scenario comprises, for example, a karaoke function, a (video) chat function, and other known or to be known scenarios. 
         [0054]    When it is determined that the current application scenario of the smart TV is the video application scenario (i.e., a first application scenario), the smart TV converts the voice signals into a corresponding operation command through voice recognition technology, and executes the operation command; specifically, in some embodiments, the operation command is an operation command of a remote controller of the smart TV, including, but not limited to, an on-off command, a volume adjustment command, a channel selection command, and the like. 
         [0055]    The smart TV stores a voice feature database in advance, wherein the voice feature database may comprise a voice model. During voice recognition, a voice feature of the voice signal is extracted, and the voice feature is searched to find a match in the voice feature database, and the match result is converted into a corresponding operating instruction. 
         [0056]    For example, when a user watches TV programs through the smart TV, the user may speak instructions such as “volume up”, “volume down” or “turn it up”, “turn it down” to adjust the volume of the TV. The user may also say “switch to another channel” to change the channel, or say “power on” or “power off” to control the power supply. The above sounds are acquired by the mobile phone and other mobile terminals and are transmitted to the smart TV through the voice channel; after receiving the voice signals, the smart TV extracts voice features therein and finds a match for the voice features in the voice feature database. The voice feature database stores corresponding relations between voice features and operation instructions, the corresponding operation instructions can be identified according to the voice features and are executed on the smart TV, so as to control the smart TV, wherein the voice features include, but are not limited to, voice cepstrum, logarithmic spectrum, spectrum, formant position, pitch, spectrum energy, and other characteristics. 
         [0057]    Moreover, when it is determined that the current application scenario of the smart TV is the karaoke application scenario (i.e., a second application scenario), the smart TV recognizes the voice signals through the voice recognition technology and finds a match for the recognized voice signals in a preset database, so as to obtain the matching result, and then the matching result is executed by the smart TV. For example, when the smart TV implements the karaoke function, the user may say the name of a song or a singer or hums a melody to the mobile phone, the above sounds are acquired by the mobile phone or other mobile terminals, and then are transmitted to the smart TV through the voice channel; after receiving the voice signals, the smart TV extracts voice features therein and finds a match for the voice features in a preset song library; a song corresponding to the song name, the singer name or the melody is identified, and the song is played on the smart TV, so as to realize the effect of quickly finding the song. 
         [0058]    In addition, when the smart TV executes the karaoke function, the user may use the mobile phone as an audio acquisition device of the smart TV and sings a song to the mobile phone; the above sound signal is acquired by the mobile phone or other mobile terminals, and then is transmitted to the smart TV through the voice channel; and the smart TV directly broadcasts the sound signal. 
         [0059]    In the above embodiments, the mobile phone is used as the audio acquisition device of the smart TV, the voice recognition technology is used to control the smart TV and the voice input of the same, and the user can then interact with the smart TV directly through this portable device (the mobile phone), so as to greatly improve the user experience of the smart TV. 
         [0060]    Some embodiments of the present disclosure are described in reference to  FIG. 2 , which comprises the following steps: 
         [0061]    In step S 202 , the wireless voice channel between the smart TV and the mobile terminal is established. 
         [0062]    In step S 204 , the mobile terminal acquires the voice signals, wherein the voice signals can be acquired through a microphone of the mobile terminal, or voice signals can be received in advance through the mobile terminal. 
         [0063]    In step S 206 , the smart TV receives the voice signals from the mobile terminal through the voice channel. 
         [0064]    In step S 208 , the smart TV receives the voice signals; the smart TV determines its current application scenario, if it determines that it is a video application scenario, step S 210  will be executed; if the smart TV determines that it is a karaoke application scenario, step S 214  or step S 216  will be executed. 
         [0065]    In step S 210 , when the smart TV is in the video application scenario, it converts the voice signal into a corresponding operation command. 
         [0066]    In step S 212 , the operation command is executed by the smart TV. 
         [0067]    In step S 214 , when the smart TV is in the karaoke application scenario, the smart TV recognizes the voice signals through the voice recognition technology, finds a match for the recognized voice signals in the preset voice feature database to obtain a matching result, and executes the matching result. 
         [0068]    In step S 216 , when the smart TV is in the karaoke application scenario, it directly broadcasts the sound signal.

When the smart TV initiates the wireless voice channel between the smart TV and the mobile terminal, the smart TV receives the voice signals from the mobile terminal through the established voice channel. 
         [0073]    The processing module  30  is used for determining a current application scenario of the smart TV, and correspondingly processing the voice signals according to the current application scenario. 
         [0074]    Further, if it is determined that the current application scenario of the smart TV is the video application scenario (i.e., a first application scenario), the processing module is used for recognizing the voice signals through the voice recognition technology, converting the recognized voice signal into a corresponding operation command, and executing the operation command via the smart TV; wherein, the operation command is an operation command corresponding to the remote control for the smart TV. 
         [0075]    On this basis, with reference to  FIG. 4 , the processing module  30  further comprises: 
         [0076]    a feature extracting module  310  used for extracting voice features of the voice signals; and 
         [0077]    a matching module  320  used for finding a match for the voice features in a preset voice feature database to obtain a matching result, and converting the matching result into a corresponding operation instruction, wherein, the corresponding relations between voice features and operation instructions are stored in the voice feature database. 
         [0078]    If it is determined that the current application scenario of the smart TV is the karaoke application scenario (namely, a second application scenario), the processing module is further used for recognizing the voice signals through the voice recognition technology, finding a match for the recognized voice signals in the preset voice feature database to obtain a matching result, and executing the matching result via the smart TV. 
         [0079]    If it is determined that the current application scenario of the smart TV is a karaoke application scenario (i.e., a second application scenario), the voice signals will be played through the sound card of the smart TV. 
         [0080]    The operating steps of the method of the present disclosure correspond to the structure features of the system, and can be mutually referenced. 
         [0081]    In summary, according to the technical schemes of the present disclosure, voice signals are received through the established voice channel, and processing of the voice signals can be carried out according to the determined current application scenario, so as to realize the interaction with the smart TV and greatly improve the smart TV user experience.
