The ISD1790SYIR (Interactive Speech Dialog) is an integrated, single integrated circuit that is used to provide solutions for interactive speech dialog applications. It is capable of working with a variety of external microphones, acoustic couplers, and other interactive sound sources. The chip is designed to capture, store, and playback voices, sounds and words. It is suited for interactive language programs, voice activated toy robots, voice response systems, and voice recognition applications.

The ISD1790SYIR integrates an on-chip microphone pre-amplifier and microphone input selection logic that allow it to drive both electric and acoustic microphones. The built-in microphone interface logic provides phase shift, noise cancellation and rejection of aliased signals. This enables the IC to capture voices and sounds perfectly. The ISD1790SYIR also contains an 8-bit digital audio recorder with a data memory size up to 400Kbits. This allows it to store and replay voices in multiple languages with up to 4 minutes of message time. The ISD1790SYIR is also capable of creating variable sounds, music and special effects.

The ISD1790SYIR can be used in various interactive speech dialog applications. It is most suited for interactive language programs, voice activated toy robots and voice response systems. In these applications, the IC works as a voice recognition controller and audio processor. The IC is capable of storing and playing back predetermined voice samples for voice recognition. It is also capable of editing, recording and playing back new samples and phrases. By using the built-in microphone input selection logic, the ISD1790SYIR can capture acoustic sounds from different distance ranges. The sound stored in the IC can then be modified to create various effects.

The ISD1790SYIR also includes a powerful string processing engine that allows it to recognize multiple languages and accents. This engine can be programmed to recognize spoken words and phrases with a high accuracy rate. The voice recognition is further enhanced by the built-in re-triggerable trigger logic and voice recognition logic that can detect and respond to inputs within milliseconds.

Overall, the ISD1790SYIR is a highly efficient and compact device for creating interactive speech dialog applications. It is capable of capturing, storing and playing back voices, sounds, and words with a high accuracy. The on-chip microphone pre-amplifier and microphone input selection logic enable it to capture acoustic sound from different ranges. The chip also includes a powerful string processing engine and re-triggerable trigger logic and voice recognition logic that can detect and respond to inputs quickly and accurately. With its wide range of capabilities, the ISD1790SYIR is ideal for interactive language programs, voice activated toy robots, voice response systems, and voice recognition applications.
