OKI Semiconductor's history in the Speech Synthesis segment spans over three decades, and its superior speech quality, as a result of the company's refined ADPCM and PCM algorithms, has assured OKI Semiconductor a leading position among suppliers of speech devices. OKI Semiconductor offers playback only, voice playback and record devices, as well as stereo audio playback and record devices.

In recent years, OKI Semiconductor has emphasized its efforts on creating next generation audio technologies to address customers’ demand for high quality audio recording and playback. Examples of such technologies are high quality audio DAC/ADC, noise reduction filters, LoudSound, Class-D Speaker Amplifiers and others.

LoudSound is an OKI Semiconductor proprietary technology that improves sound quality and loudness for handheld applications that use very small speakers. It works in the digital domain, thus no additional tweaking of customer’s analog design is required.

All products are supported with easy-to-use evaluation/development tools and by our top-of-the-line technical staff.
