VR Stamp™ With Serial EEPROM Speech Recognition Module Data Sheet Description Sensory’s VR Stamp™ simplifies the design of speech recognition products by integrating all key components into a convenient 40-pin DIP footprint module. A low-noise audio channel and standardized footprint allow rapid prototyping, less debugging and shorter time to market. Features FluentChip™ Capabilities Noise-robust Speaker Independent (SI) and Speaker Dependent (SD) recognition Many language models now available for international use High quality, 2.4-7.8 kbps speech synthesis & sound effects with Sensory "SX" synthesis technology Speaker Verification Word Spot (SVWS) Noise robust voice biometric security 8 voice MIDI-compatible music synthesis Audio Wakeup from sleep Touch Tone (DTMF) output Integrated Solution RSC-4128 Speech processor & 1Mbit Flash 128Kb serial EEPROM for data 14MHz (main) & 32kHz (time keeping) clocks 24 I/O lines Microphone preamplifier Pulse Width Modulator (PWM) for Speaker and optional DAC output Low Power Requirements VDD = 2.70V – 3.6V IACT = 26mA @ 3V (typ. for complete module) ISLEEP =
