Introduct voice circuit With the development of society and technology, the modern electronic products design pays great attention to product the easy operational type, the man-machine contact surface certainly to have to be good. The sound, the image and so on make the most important method which associates with the humanity, also is manifested in the electronic products design. Uses a pronunciation chip, lets the product open the mouth to speak, may get up strengthened function and so on propaganda brand, instruction user use, breakdown urgent prompt, entertainment, novel causes the product design to be practical, to forestall opponent by a show of strengthen feats the enemy by a surprise attack. Different product functional design and market demand, when design must correctly select the different pronunciation chip or the module achieves the best natural price ratio. Engineer may from following several aspects consider which kind of type selects the pronunciation chip After first, the pronunciation content transcribes the pronunciation chip, whether the content does have frequently to revise: If the pronunciation content frequently must revise, for example, recording greeting card product design and so on the electronic message machine, should use the ISD series or the APR series pronunciation recording and sending out electric circuit, these two kind of chips all support no matter what records, falls thee lectricity pronunciation content not to be able to lose, some 10second -16 minute each kind of different chip may supply the choice. The acoustic fidelity is better, may approach the magnetic tap eacoustic fidelity. If after the pronunciation content reads in does not need to revise, may consider uses OTP (disposable fever to write) the pronunciation electric circuit and to cover the membrane pronunciation electric circuit Second, how chooses OTP perhaps the MASK pronunciation electric circuit: How these two center selects, then mainly reads the order form t
