Embodiment Construction

[0011] There are two possible approaches to speech and music synthesis. One is to treat music as speech. That is, two-channel speech (two-channel speech), one is the recorded voice, and the other is the background singing. Another kind of melody is generated by a melody generator, and then mixed with voice. The method is simpler than the former, but it cannot express the effect of singing. The key point of the present invention is how to utilize the process of switching voice and music, so that the voice recorded by the card has background music or sound effect. In order to allow the card issuer to add his own voice at will, the present invention proposes three possible embodiments especially for the part of voice and music synthesis.

[0012] figure 1 It is a two-channel processing method, which treats background music or sound effects as general voice processing. figure 1 A functional block diagram of an IC mounted on a card is shown. There is a background signal storag...

Abstract

The present invention is used in card to increase its scene Phonetic signal is first converted into digital signal and encoded in compression mode by a compression device and then stored in a memory. For increasing background music or music effect, background signal is pre-recorded in a memory or one instead music effect generator is used. During re-play, phonetic signal is first decompressed and then treated by fader to output mixed signal. Finally, the mixed signal is converted into analog signal to produce sound with background music.

Description

technical field [0001] The present invention is a method and device for synthesizing speech and sound effects applied to a card, so that the card not only has the function of recording and playing sound, but also adds the effect of background music. Background technique [0002] The audio recording and playback cards that are common in the market today have the functions of recording and playback, so that the card issuer can record the voice on the card in advance, and then send it to the recipient to transmit the audio message. This kind of recordable sound card has a wide range of uses, and can be used for festival greeting cards of scenes, commemoration of special festivals, greetings from friends, etc. When the recipient flips through the card, the sound playback device can be touched to play the card issuer's audio message. [0003] Cards of this type usually include a recording and playback integrated block (IC), which is used to convert the voice into electronic sign...
