Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an audio output device that outputs pre-stored audio information in response to an audio output request.

Conventional audio output devices have the function of appropriately selecting audio information pre-stored in a storage device provided in response to an external audio output request and outputting the audio through the audio generator. When an audio output request is input, the previous audio output is aborted at that point. Therefore, if conventional output requests are used in applications where output requests occur one after another at short time intervals, the audio output will be interrupted continuously. It had the disadvantage that it was difficult to hear what was happening.

For example, in an office computer equipped with a voice output device, when the voice output device reads out input item names and the user inputs numerical values accordingly, the more proficient the user is with key operations, the less time it takes to input numerical values. The audio output was frequently interrupted, causing inconvenience and discomfort to the user.

It is an object of the present invention to provide an audio output device that automatically outputs audio at an appropriate speed in response to the cycle of audio output requests.

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

FIG. 1 is a block diagram showing the configuration of the audio output device of the present invention, and 2 is an input terminal for inputting an audio output request and address information, and the audio output request and address information input from this input terminal 2 are is output to the central processing unit B. The central processing unit 3 controls the devices described later, and reads audio information from the storage device (14) according to the address information inputted from the input terminal 2.The storage device 4 is shown in FIG. Voice information is recorded in the order of addresses as shown in FIG. 6, and one central processing unit 6 outputs the voice information addressed.

The audio information read from the central processing unit 6 is transmitted to a speaker, which is an audio generator, via an audio control 6 that converts the audio information into an audio signal, according to the speed of the time axis conversion device 5 that determines the audio output speed. It is output from 7.

Here, the time axis conversion device 5 is already known, so a detailed explanation will be omitted, but it has a function of removing pitch changes that occur when audio is played back at a speed different from that at the time of recording by expanding and compressing audio data on the time axis. has.

The speed setting for the time axis conversion device 5 is performed by the central processing unit 6 in accordance with the contents of the auxiliary storage device 8 that stores speed information.

The auxiliary storage device 8 is reset by a reset signal input from the terminal, and is incremented by one by the central processing unit 6 depending on the state of the flip-flop 9 indicating that audio is being output.

The entire operation of the central processing unit 6 is explained in detail in the flowchart of FIG.

The principles are as follows.

1) Frisoge flop F is set at the start of audio and reset when audio output ends or is interrupted.

I) The contents of the auxiliary storage surface M are incremented by 1 each time an audio output interruption occurs within a range not exceeding a certain value.

The operation of the audio output device of the present invention shown in FIG. 1 will be explained below according to the flowchart shown in FIG. is the basic speed, 1 represents 1.5 times the speed, and 2 represents twice the speed.

At this time, when audio output requests are input from terminal 2 in the order of addresses 0.1.2, . . . at intervals of 2.5 seconds, the result is a timing chart as shown in FIG.

However, it is assumed that the audio output in FIG. 1 requires 6 seconds at the basic speed, and the auxiliary storage device 8. :I: The initial value of the flip flop 9 is '1-'.

(1) When an output request for address 0 occurs at time 1, since the auxiliary storage device 8 and the flip-flop are at D, the audio output "product name code...misery" starts at the basic speed, and the flip-flop 9 is set to 1. (5tep 145
tep 5 → 5tep 945tepIQ).

Audio output lasts 6 seconds.

(Ii) A voice output request for address 1 occurs at time 6.5, 2.5 seconds later.

At this time, flip-flop I- is at (1), so audio output is interrupted and flip-flop F is reset to (0).

Next, since the auxiliary storage device M is O, it is increased by (1) and becomes (1). (1) indicates a speed of 1.5 Buddhas, so 1.
5 times faster time axis conversion, 1! ! , :fjt5 is set to start audio output, and the flip-flop F is set to (1). Audio output lasts for 2 seconds (Step

At this time, the audio output has already ended and the flip-flop) is (0), so '+M, auxiliary memory 1-+5t

.

Since the content of the auxiliary storage device is (1), the audio output continues for 2 seconds.

After (1v), this state is maintained until the output request stops, so that audio output at a speed corresponding to the cycle of the output request is guaranteed.

As described above, according to the present invention, it is possible to provide an audio output device that can output audio at an appropriate speed in accordance with the cycle of audio output requests.・
