Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a voice generator that stores an arbitrary language and reproduces the voice as necessary.

2. Description of the Related Art Conventionally, devices that store language in an electronic device and make it speak at will have been highly evaluated in the market as a device that issues detailed signals and alarms.

P However, because there is a limit to the amount of language that can be memorized,9 the range of use of each device is restricted, and it is necessary to manufacture products for each use and purpose. Therefore, the reality is that its functions and effects cannot be practically used for anything other than things that have many uses.

The present invention aims to solve this problem. Language is stored as each element, and the user can arbitrarily compose a language using one element, thereby making it possible to use a voice generator for purposes that could not be used in the past. The aim is to make it available for use. The range of applications of speech generators is wide, such as expressing the will of a deaf-mute or sending a message to a child, and in the case of devices with a large amount of memory, by expressing a large number of signals individually as language, it is possible to identify them. This will expand greatly and increase the number of people who will benefit from it.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a conventional speech generator, in which 1 is a speech synthesis element, 2 is a speech-only memory, 5 is a speaker, and 4 is a speech-dedicated memory by controlling the speech synthesis element 1. Memory 2 and speaker 5
This is a microcomputer for operating the . In the case of a conventional device, a predetermined language is stored in the audio-only memory 2. In response to this, signals as the sound source pitch, reflection coefficient, and volume of the language in the audio-only memory 2 are input to the speech synthesis element 1 by a command from the microcomputer 40 . In the speech synthesis element 1, the sound is classified into voiced and unvoiced sounds based on the pitch of the sound source, and the amplitude is changed depending on the volume.The sound is then outputted through a digital filter formed by each reflection coefficient, a digital-to-analog converter, and an amplifier. This output signal is emitted by the speaker 3. In this case, since the audio-only memory 2 has a limited storage capacity, the languages that can be stored therein are limited. Therefore, in order to carry out conversations in everyday life, a memory with a huge storage capacity is required. Therefore, the present invention has a configuration as shown in FIG.

In other words, the JP-A No. 5
8-18698 (2) A memory 5 is provided, and a key operation section 6 is further provided in the preceding stage. The key operation unit 6 has a function of extracting signals of individual language elements.

For example, signals for the individual elements "a" and "power" of the word "red" are extracted and stored in the memory 5. Here, the keyed-in signal as a language element is generated by the voice signal from the microcomputer 4.
Speech synthesis element 1 as sound source pitch, reflection coefficient and volume.
In this case, the "red" sound is heard from speaker 3.
is uttered from. In this case, the memory 5 only stores the array of elements as a language, and the audio-only memory 2
Since it is sufficient to store only the signals of the language elements shown in FIG. 3, it is possible to perform the language utterance required by the user without requiring a huge storage capacity as in the conventional case.

As described above, according to the present invention, the signal arrangement of each element of a language is stored in a memory, and this is inputted to a speech synthesis element via a speech-dedicated memory according to instructions from a microcomputer and outputted as speech. As a result, elements of any language can be retrieved by operating the key operation section, and the storage capacity of the voice-only memory is also small.

Note that the specific configuration of the key operation section may be appropriately selected from those having conventional key operation functions.
