Our clients span healthcare, education, legal services, and sales enablement. Each came to us with a voice-first challenge—poor audio capture, unreliable transcription, or hardware that didn’t meet privacy, performance, or scale requirements. Below are four examples of how we helped them bring better voice interfaces to life—without naming names.
AI Sales Coaching Device
Challenge: A sales-tech company needed a discreet, wearable microphone to record in-person customer conversations and stream them to an AI-powered coaching platform. Off-the-shelf mics delivered low accuracy and lagged in real-time feedback.
- Solution: Designed a 3-mic directional array in a clip-on badge form factor, tuned for clarity in retail and call center environments.
- Noise suppression: On-device DSP reduced background noise by ~40%, boosting transcription accuracy.
- Latency: Processed and streamed voice data with <50 ms delay for real-time coaching triggers.
Impact: Reduced transcription errors by 35%, enabling faster coaching loops and deployment across pilot locations within 60 days.
Secure Voice Capture for Legal Compliance
Challenge: A legal-tech company needed a portable, tamper-proof mic that could record field interviews with encryption and offline storage—compliant with strict chain-of-custody protocols.
- Solution: Developed a handheld mic with a tactile “record” toggle, secure local storage, and auto-encryption firmware.
- Privacy-first design: Audio was only recorded when activated and erased after encrypted upload via secure mobile app.
- Durability: Built shock-resistant housing with long battery life for all-day use.
Impact: Replaced vulnerable smartphone recordings with a compliant, standalone device that streamlined interview collection and met audit and legal standards.
Lecture Capture & AI Summarization
Challenge: An education platform needed hardware for lecture capture that would transcribe spoken content and summarize it for student use—all without human note-takers or transcription editors.
- Solution: Engineered a 4-mic beamforming array embedded in a podium system, designed for 2–3 meter voice pickup with minimal background noise.
- Intelligent pipeline: Device streamed real-time audio to a cloud transcription and summarization engine, triggering chaptered outlines and highlight reels.
- Plug-and-play integration: Firmware included wake-word activation and silence trimming to focus only on relevant content.
Impact: Delivered 98% transcription accuracy in classrooms and meeting halls, saving faculty hours of post-session work and improving student retention with instant summaries.
Remote Patient Audio for Telehealth
Challenge: A healthcare technology company needed secure, high-quality voice capture for remote patient monitoring. The solution had to protect privacy, integrate with existing EHR workflows, and work reliably in patient homes.
- Solution: Designed a small-footprint mic system with on-device encryption and secure cloud transmission, optimized for conversational range audio.
- Privacy controls: Built firmware with silent activation modes and automatic data deletion post-upload, ensuring HIPAA alignment.
- Clinical integration: Voice notes fed directly into patient records and remote diagnostic tools.
Impact: Enabled clear, secure voice assessments in home settings, reducing nurse follow-ups by 20% and improving adoption of telehealth across older patient groups.
