Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an audio output device (for example, an audio alarm clock, an audio output type calculator, an audio alarm tester, etc.) that outputs numerical information to be output by audio, and particularly relates to an audio output device that outputs numerical information to be output by audio. To provide an audio output device configured so that when outputting numerical information from the device, the numeric value immediately before the decimal point can be uttered more naturally.

Generally, when numerical information is output as voice, the numerical value as voice can be constructed by combining several phonemes.

For example, "Yon" in 40 (Yonjiyuu) and "Yon" in 4o0 (Yeonhyaku) use common voice data, and then add the voices of (Jiyuu) and (Hyaku) to make 40 (Yonjiyuu) and 400( Yonghyak) can be output as audio. Furthermore, simply 4 (Yon) can also be used as the above (Yon). That is, most of the voice data of one-digit numerical values from 1 to 9 can be shared, even if the tens digit, hundreds digit, or thousand digit other than the ones digit is used. Also, when outputting audio including numbers below the decimal point, the ones place (san) of 123.4 is the hundreds place (san) of 321.4, and the
31. A common data can be used with the positive digit (san) of 4. However, the ones place of 132.4 is 2
Research has revealed that it is a different sound from the hundreds place (: in 13.4) and the + (+) place in 123.4.
It is more natural to pronounce the 2 just before the decimal point as nii) than to say the decimal point.
・,'・ Compared to our usual pronunciation (Hyakusanjiyuuniitenyon), it sounded very literal and I didn't like it.

This phenomenon also occurs for the number 5 as well. In other words, the 5 immediately before the decimal point is pronounced (go-oh), and the other 5
It is pronounced like ``ha'' (go). In the present invention, when outputting numerical information including a decimal part, "2" or "5" in the first integer part (that is, immediately before the decimal point) is changed in other cases (including other digits and the decimal part). ``2'' or ``integer part 1) of numerical information
The above-mentioned problem has been solved by configuring the system to output a voice that emphasizes vowels more than the voice that is used when outputting ``5''.Hereinafter, one embodiment of the present invention will be described with reference to the drawings. .

In the embodiments to be described, the present invention is implemented with respect to parts common to an audio alarm clock, an audio output calculator, an audio alarm tester, and the like.

FIG. 1 is a block diagram of this embodiment. In Figure 1,
X is a numerical data storage register, and X is a decimal point position storage register, both of which are configured in a RAM (random access memory).

0C is an output control circuit that extracts the contents of register X in the order of audio output and outputs it to buffer B for one digit;
, is the value output to buffer B, that is, the value to be outputted from now on, based on the decimal point position stored in This is an output digit detection unit that determines whether or not the numerical value is in the ones digit and there is a numerical value below the decimal point. J1 outputs a signal Sy if there is a value below the decimal point and the content of B is a value in the ones place, and otherwise outputs a signal SN. J2 means that the content of B is “2
”, and if it detects “2”, it outputs a signal S2. Also, for J5, the content of B is “5
”, and if it detects “5”, it outputs a signal S5. Gl, G2, G3, and G4 are code selection gates, and G outputs the code C2O to the gate G5 when the signals S2 and SN are both generated;
is the code C2l when the signals S2 and Sy occur together.
is output to the gate G5, and G3 outputs the code C and O to the gate G when the signal S5 and the SN force {both occur,
G4 generates code C5 when signals S5 and Sy occur together.
, is output to gate G5. Gate G is
The contents of buffer B are supplied to the code converter CC, but if J2 detects "2" or J5 detects "5", either code C2O, C2 or C5O, C, l is sent. Supply to CC. CC is a code converter, and G5
The start address of the voice corresponding to the code outputted from (the content of B is also one of the codes) is generated. VR is an audio data storage unit that stores data that is the basis of audio,
AC is its address counter and AD is its address decoder. DA is a digital-to-analog converter.
The above-mentioned code conversion section CC) storage section VR) address counter AC) address decoder AD) and digital-to-analog conversion section DA constitute a voice synthesis section VCC. This is an SP audio output section. For example, if the contents of register X are 1324 and the contents of register In this case, J1 is the signal S since the signal S1 is in the ones place and the content of X is other than 0.
Output y. Further, J2 outputs a signal S2 which detects that the content of B is 2. Therefore, gate G2 is opened and code C2l is output. As a result, the code converter C
C generates the start address for outputting (Ni) as voice, and AC counts up the VR address (Ni).
output as audio. Further, if the content of X is 132 and the content of X is o, then 132 is stored by X and X.

In this case, if the ones digit is output to buffer B, the signal S
N and S2 are generated, and the code C2O is outputted to the code converting section CC, which is output as audio. In the case of 5, the same operation is performed, and if there is a number below the decimal point and the one digit is 5, (go) is outputted as voice, and in other cases, (ko) is outputted as voice.

In addition, in order to simplify the explanation of the above embodiment, (Hyaku),
I have omitted the control section for the voice output of the decimal point (10), etc., but as shown in Fig. ,
If the scale word code or the decimal point (ten) code is generated by the scale code generator TC, and the code is supplied to the code converter CC via the gate G, It is possible to output words such as aloud. In addition, the voice synthesis unit VCC shown in FIG.
Although it has a configuration that performs conversion, patent application No. 54-19309
In the method proposed in , which synthesizes a desired speech waveform by applying fluctuation operations such as pitch period, amplitude, and time axis correction to the basic phoneme data, common phoneme data is used and its By changing the variation operation, it is also possible to distinguish between eyes and (nii) or (ko) and (go) and output the sounds.

As explained above, when the audio output device of the present invention outputs numerical information, a specific number (2 or 5) immediately before the decimal point outputs a sound that is different from the audio output of that number in other cases. By doing so, it is possible to provide natural and clear voice notification without increasing the storage capacity of the voice data storage unit as much as possible.
