Why speech intelligence matters now more than ever?
Modern investigations are drowning in a flood of disjointed audio evidence. Phone calls, meeting recordings, and voice notes sit siloed in countless systems, making it harder than ever to connect the dots when time is critical.
Exponential audio data
Manual review of audio is infeasible due to sheer volume.
Multilingual complexity
Diverse scripts and languages challenge accurate transcription.
Voice as evidence
Audio is critical evidence, but extracting reliable insights remains challenging.
Time-critical cases
Slow speech decoding can delay urgent investigations.
Seamless intelligence integration
Speech data must integrate seamlessly with other intelligence systems.
Translation gaps
Missing translations leave critical multilingual evidence unusable.
