Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an audio output editing method, and more particularly to an improvement of an audio output editing method that controls output time according to the unit length of two clauses, one phrase, one word, etc. that make up a sentence.

Japanese language processing equipment is used in computer systems, and various attempts have been made to use convenient and easily available voice as an input/output means for this processing equipment, and these have generally been effective. The one shown is used. In this method, a sentence output from a Japanese language processing device 1 is input into a buffer circuit 2, and a speech generation control circuit 4 receives pit information from the buffer circuit 20 that specifies the phoneme, and generates a sound that electronically determines the phoneme. Convert to make. This meter is input to the conversion circuit 5 and converted into an analog signal.The conversion circuit 5 further outputs an instruction to the phoneme clock circuit 6.The phoneme clock circuit 6 determines the duration of the phoneme and The generation control circuit 4 is driven to instruct the phoneme transition i time.The sound output from the Hiro conversion circuit 5 is inputted to the voiced sound source circuit 7 and the unvoiced fricative sound source circuit 8, and is output as sound from the speaker 10 via the amplifier 9. Although the speech synthesizer 3 shown above is one example, the speech synthesizer of the local format also generally determines the duration of the uttered phoneme on a per phoneme basis, and of course exhibits a considerable effect. However, the units that make up the Japanese language, such as 1 clause, 0 clauses, and words, are defined by the number of phonemes included in the syllables, and the disadvantage is that it is not possible to generate one phoneme in 9 speech output times. there were.

The present invention was developed in view of the above-mentioned drawbacks.The present invention provides an audio output editing method that can improve the quality of audio output that is easy to listen to and edit by defining the phoneme duration based on units in a sentence when speaking Japanese. The purpose of this is to give people the benefit of the world. To briefly explain the present invention, the present invention includes a decoder circuit in the 2771 circuit to decode the unit length of the sentence in the buffer circuit, and if the sentence unit is long, it will be short, and if the sentence rate is short, it will be expanded and the phoneme clock will be generated. This feature is characterized in that the sound output is controlled.

Preferred specific examples for carrying out the present invention will be described in detail below with reference to the drawings. FIG. 2 is a block diagram of an embodiment of the audio output editing method of the present invention, and is the same as FIG. 1.
The same reference numerals will be used for the tubes, and the description thereof will be omitted. 1
1 is a decoder circuit, and 12 is a clock conversion circuit. One of the features of the present invention is the clock conversion circuit 12, and the clock conversion circuit 12 has conversion characteristics as shown in FIG. 3, for example. The horizontal axis represents the number of sound nests in the units that make up the sentence, and the vertical axis represents the elapsed time to generate the unit in units of 1<m), and the utterance duration of one phoneme at that time is expressed as a gate curve. The decoder circuit 11 resolves the unit length of the Japanese sentence stored in the buffer circuit 2 and indicates the horizontal axis in FIG. 3, for example, 4. The clock conversion circuit 12 that receives the instruction No. 4 drives the phoneme clock circuit 6 so that the phoneme of the unit is uttered at the time of point 1 in FIG. 3, and the entire unit is uttered within the time of point A. be. As is clear from Fig. 3, long phonemes of sentence units, such as 2 clauses, 0 phrases, and words, are uttered shorter, and shorter units are uttered longer. Of course, a division is provided between units, and the above-mentioned clock conversion is performed during this interval.

As is clear from the above explanation, the present invention is an audio output editing method that controls the continuation of the utterance of a phoneme in accordance with the change in the utterance duration of each phoneme and the length of a sentence unit, making it shorter for long sentences and longer for short sentences. If this is applied to a Japanese language audio output device, it will be extremely advantageous in terms of improving audio quality.
