Abstract

PURPOSE:To enable voice editing so as not to include signal components of prescribed frequencies by converting the inputted analog voice signals to digital signals, detecting signal components of the prescribed frequencies and displaying these signal components so as to distinguish them from others. CONSTITUTION:In order to make a voice guidance, the voice signals which become the basis are recorded in a tape recorder 12. This recorded analog signals are sent to a signal processing device 20 through a voice input device 10. When the signal processing device 20 is inputted these analog signals, these signals are digitally encoded and the device simultaneously detects for PB signal components and these are sent to a main device 40. When the main device 40 receives these digitally encoded voice signals, it displays these signals in a display device 42 in terms of graphs and should the PB signal components be included in these voice signals, these parts are displayed, as an example, in red so that these can be distinguished from others.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the voice guidance production apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a functional block diagram of the voice guidance creation device in this embodiment. The audio guidance creation device is a device that digitizes and edits input analog audio signals, and as shown in the figure, includes an audio input device 10, a tape recorder 12, a speaker 14, a signal processing device 20, a main device 40, and a display device. (CRT) 42,
Keyboard (KB) 44 and floppy disk device (
FDD) 46. Signal processing device 20
has a function of compressing/encoding/decompressing an analog audio signal, a function of detecting a PB signal, and a function of transmitting/receiving digitized information to/from the main device 40. The main device 40 also includes a central processing unit (CPU) and a main memory (M
M). That is, the main device 40 displays digital audio data on a display device 42, edits audio according to commands input from a keyboard 44, and stores encoded audio data in a floppy disk device 46, for example. Furthermore, the operator 70 is an operator who operates this system.

Next, the flow of creating voice guidance in this embodiment will be described using FIG.

[0013] When creating the audio guidance, the audio signal that is the basis thereof is recorded on the tape recorder 12. The analog signal recorded on the tape recorder 12 is sent to the signal processing device 20 via the audio input device 10. When the signal processing device 20 receives an analog audio signal, it digitally encodes this signal, simultaneously detects PB signal components, and sends these to the main device 40 (101). When the main device 40 receives a digitally encoded audio signal, it displays this signal in a graph on the display device 42, and if this audio signal contains a PB signal component, it distinguishes it from others. That part is displayed in red, for example, so that it can be viewed (102).

For this reason, the operator 70 uses the tape recorder 12
If the PB signal is included in the analog signal recorded in the PB signal, it can be confirmed by looking at the display device 42. If the analog signal contains a PB signal,
The operator 70 edits the audio guidance for the purpose of creating audio guidance that does not cause erroneous detection of PB signals. That is, the operator 70 operates the keyboard 44 to request the main device 40 to issue correction commands such as removing, silencing, or lowering the audio level of the audio portion having the same frequency as the PB signal displayed in red on the display device 42. (103).

When the main device 40 receives the modification request from the operator 70, it processes the digitally encoded audio data according to this command, and sends the processed audio data to the signal processing device 20 (104, 105). The signal processing device 20 restores the processed digital code audio data to an analog audio signal and sends this analog audio signal to the audio input device 10. The audio input device 10 is a signal processing device 20
When an analog audio signal is inputted, this signal is outputted to the outside by the speaker 14. At the same time as this processing, the signal processing device 20 also notifies the main device 40 whether the restored analog signal includes a PB signal (106
). If the PB signal component has not been removed, it is displayed in red on the display device 42 (107).

[0016] This allows the operator 70 to listen to the processed audio guidance and also to confirm the presence or absence of the PB signal component. For example, if the processed audio guidance is unnatural or the PB signal component has not been sufficiently removed, the operator 70 repeats the editing work (108). After performing such editing work, when the digital audio data of the audio guidance is completed, it is encoded by the signal processing device 20 (109, 110). The encoded audio data is sent to the main device 40 (111), and stored in the floppy disk device 46 by the main device 40 (112).

As described above, according to the voice guidance creation device according to the present embodiment, the compression encoding/decoding function and the PB
By providing a signal component detection function and a graph display function on the display device, the PB signal frequency component included in the voice guidance is detected and displayed in a graph on the display device 42 at the same time, and the PB signal component can be removed, muted, or voiced. The level can be lowered without impairing naturalness. Although the present embodiment has been explained using the detection and editing function of the PB signal component included in the voice guidance as an example, the present invention is not particularly limited to this, and the system to which the voice guidance is connected is connected to other systems. When operating based on frequency signals, a function for detecting and editing such frequency signal components may be provided.

[0018]

As described above, according to the voice guidance creation device of the present invention, it is possible to provide a voice guidance voice file in which signal components of predetermined frequencies in the voice band are substantially removed. Therefore, by using the voice guidance created according to the present invention, it is possible to substantially remove a signal component equivalent to a predetermined frequency signal component in the voice band in which system operation is performed, thereby preventing erroneous operation of the system due to voice guidance. It becomes possible to do so.

According to the present invention, when creating an audio file, a predetermined signal component is removed, silenced, or the audio level is lowered based on the graph displayed on the display device. By using , it is possible to respond precisely to audio editing, and the audio signal can be immediately played back and checked using the processed data.
