Summary of Lattice FPGA Voice Processors
Lattice offers a low-power, always-on voice solution for smartphones and consumer electronics. It combines "Voice Command" IP for hands-free activation with "Voice Recognition" IP to enhance security and reduce false triggers. The system includes Human Voice Detection to distinguish human speech from other sounds, Voice Biometrics to verify the authorized owner's unique signature, and Voice Command Learning to recognize specific spoken commands by the user.
Parts used in Lattice Voice Solution:
- Voice Command IP
- Voice Recognition IP
- Human Voice Detection component
- Voice Biometrics module
- Voice Command Learning module
Voice Detection & Recognition Solutions
Enabling Always-On Voice Input Applications While Maximizing Battery Life
Low Power, Always-on, Accurate, Responsive
Consumers increasingly want to use voice commands to interact with their smartphones and other consumer electronic devices. Enabling reliable and accurate voice input applications while simultaneously minimizing the impact to battery life is a clear priority for manufacturers.
Lattice’s Voice Solution consists two IP: “Voice Command,” which supports hands-free and always-on applications, and “Voice Recognition,” which improves the user experience by enhancing security and reducing false trigger inputs.
| Function | Description | Purpose |
|---|---|---|
| Human Voice Detection | Discriminates a humans voice from other voice band signals | Determine if a sound is human |
| Voice Biometrics | Identifies the unique voice signature of one person; Enables voice passwords | Determine if the voice heard comes from the authorized device “owner” |
| Voice Command Learning | Identifies and remembers a single spoken command | Determines if a special command has been spoken by the “owner” |
