Description of the invention

The invention relates to the field of recognition of speech signals and is intended for the creation of a voice-controlled telephone 2 answering machine of a public telephone network.

Analogues of the invention include methods of controlling a telephone answering machine set-top box of a public telephone network based on the use of buttons and a screen. The disadvantage of this method of control is the complex structure of activating the answering machine functions, which is a result of the limitation of control tools in portable desktop devices. Another drawback is the need to remember the phone number 70 of the desired subscriber or the complicated procedure of searching for it in a regular electronic telephone directory.

There are several types of public telephone network answering machines, but there are no public telephone network answering machines with voice control of functions and connections. Therefore, the prototype was chosen for the method of controlling the telephone 12 secretary-set-top of the public telephone network EHREKT (m/mlmy(eIevzuz.gy/ehregi. pit). which is controlled using four control buttons and a liquid crystal screen. The device is controlled using a menu. Accordingly, in each of the menu items, the functions of the control buttons and the assignment of special marks on the liquid crystal screen change.

The disadvantage of the prototype is the multi-level process of managing functions. Due to the large number of menu items, states of the liquid crystal screen and different functions of the buttons for different menu items, controlling the device requires a lot of initial preparation. Another disadvantage is the difficulty of searching for entries in the telephone electronic directory. The reason for these shortcomings is the established technology of screen, visual and tactile control, instead, this invention offers another, voice control of the functions of the answering machine-set-top box. p. 29 The invention is based on the task of improving the process of managing the functions of the answering machine by implementing voice command recognition technology, which allows you to control the functions of the answering machine with natural language and organize the telephone electronic directory with the inclusion of voice identifiers.

The invention offers a fundamentally new, absent in the prototype, method of controlling the functions of a telephone secretary-set-top box. So, to implement the function of initiating a telephone call in EHREKT, press one button twice, then use the second and third buttons to find the desired entry in the phone book, then press the fourth button. In the invention, in order to initiate a phone call, you can only call the caller's voice ID. In addition, you can initiate a call in the traditional way using the /-|h keys, if the speech recognition mode is previously disabled. To make a telephone connection by 3o the last dialed number in EHREKT, press the first button three times, then press the fourth button. eh

In the invention, in order to make a connection by the last dialed number, you can only say a command, for example, "LAST DIALED", and the traditional method of establishing a connection by the last dialed number using keys is also provided. In general, in the invention, voice commands can "F" perform the functions of establishing a connection, all functions of working with a telephone electronic directory, with an automatic number identifier, a digital answering machine. By the way, the prototype does not contain a telephone answering machine at all.

With" The most important innovation of the invention is the method of implementing control of the answering machine-set-top box with the help of the user's voice commands. This method of management guarantees convenience, speed and simplicity in managing the device for the user

Control of the functions of the voice assistant - set-top boxes can be performed using voice commands. /5 For this, the command and/or voice identifier of the subscriber to be called is called.

The result of the command, prompts or detected errors can be announced in the form of voice messages next to the screen display. The subscriber is named during the formation of the telephone electronic directory.

To do this, the name of the subscriber is pronounced. A record containing the subscriber's telephone number, his text identifier and may contain a voice identifier is stored in the telephone electronic directory.

If the record contains a voice identifier, then calling this subscriber or editing a record of the telephone electronic directory can be done by saying the voice identifier. You can also call any correspondent by saying the digital number of the correspondent in the telephone network.

Figure 1 shows the sequence of action of the voice control command. The sound signal enters the sound analyzer, in which the signal is converted to a form acceptable for recognition. In the recognition unit, the converted signal is compared with command standards stored in the non-volatile memory of the voice i) answering machine, as a result of which either a control signal for the functions of the telephone answering machine is generated or recognition is refused. In the event that the voice command needs further clarification or confirmation of the action, a dialogue between the device and the person may occur. "- zo The proposed method of voice control of the functions of the answering machine set-top box made it possible to implement the function of voice control of the device. at
