Voice IC program development

Voice chip definition

We are an agent of Sonix's full range of voice ICs, and we can develop voice toys and electronic products for customers.

The voice signal is converted into a digital by sampling, stored in the ROM of the IC, and then the digital in the ROM is restored to a voice signal through the circuit.

According to the output mode of the voice chip, it is divided into two categories, one is the PWM output mode, and the other is the DAC output mode. The PWM output volume cannot be continuously adjusted, and it cannot be connected to an ordinary power amplifier. At present, most voice chips on the market are PWM output. . The other is that the DAC is amplified by the internal EQ. The sound of the voice chip is continuously adjustable, can be adjusted by digital control, and can be connected to an external power amplifier.

The playback function of ordinary voice chips is essentially a DAC process, and the ADC process data is completed by the computer, including the sampling, compression, EQ and other processing of the voice signal.

As a leader in the development of voice controller ICs in Shenzhen, Zuchuang uses innovative technology to reduce costs and increase functions, and develops high-second voice/melody ICs, high-point LCD voice/melody ICs, green environmental protection and power-saving music ICs, 4/ 16/24 multi-channel voice/music ICs, high-compression high-quality sound DSP ICs, etc., are widely used in interactive toys, educational toys, handheld game consoles, electronic dictionaries, e-books, and various applications that require voice, sound, and melody product.
