MSM6679AL-110 Voice Recognition

Nov. 1998

SI/SD Voice Recognizer, Recorder/Player, and Speech Synthesizer

GENERAL DESCRIPTION

The MSM6679AL-110 Voice Recognition Processor (VRP) is a slave-mode device that performs

five func-tions: speaker-independent (SI) voice recognition, speaker-dependent (SD) voice

recognition, solid-state sound recording, sound playback, and speech synthesis. The highly

integrated device also provides an on-chip memory controller, Flash memory interface, analog

data conversion, Oki speech synthesizer interface, and pulse width modulation (PWM) sound

output.

For SI recognition, the MSM6679AL-110 contains a vocabulary template in external memory.

Pretrained SI vocabularies eliminate the need for laborious training, as usually required by SD

products. The memory requirements are dependent on the size of the vocabulary. The

MSM6679AL-110 can tolerate background noise, while providing high recognition accuracy. In

its designated operating environment, the device achieves a typical recognition accuracy of

>95% (using an Oki-defined test procedure).

For SD recognition, the MSM6679AL-110 stores SD vocabulary templates, as defined by the user,

in external SRAM. The MSM6679AL-110 can create SD vocabularies of up to 61 words each, with

each word using approximately 50 bytes.

In addition to providing voice recognition capabilities, the MSM6679AL-110 integrates a solid-

state recorder/player, speech synthesis functions, and a tone generator. ADPCM recording/

playback provides high quality sound and efficient memory utilization. The MSM6679AL-110

can respond to spoken com-mands, verbally or with tones, via an on-chip speech synthesizer and

tone generator. For larger speech-synthesis requirements, the MSM6679AL-110 also provides a

glueless MSM665x control interface for off-chip speech synthesis.

The MSM6679AL-110 can interface to any application or personal computer via a serial interface

through an open, device-independent serial mode API (SMAPI). To accelerate code development,

Oki supplies an evaluation kit, and assembly and C language programs for this product.

The MSM6679AL-110 is a low power version of the MSM6679A-110.

Note:

This device is intended for use in applications other than central office communication

systems and central office switching systems.
