SleekVoice

Executive Summary

SleekVoice is a native macOS application that eliminates typing by converting spoken words into polished, production-ready text — almost instantly.

Built on top of Modulate’s Velma-2 Streaming Speech-to-Text API, SleekVoice delivers professional-grade, real-time transcription through a lightweight, elegant interface that stays completely out of the user’s way.

While products like Wispr Flow have validated voice dictation as a mainstream productivity category, SleekVoice differentiates itself through deeper speech intelligence, including:

  • Emotion detection
  • Accent recognition
  • Speaker diarization
  • PII / PHI tagging

All powered by Velma-2, built on Modulate’s industry-leading speech infrastructure.

The Problem

Modern knowledge workers spend hours each day typing — emails, documents, notes, and messages.

Yet:

  • Speaking is 3× faster than typing
  • Verbal expression is often more natural for ideation
  • Existing dictation tools are limited and fragmented

Current solutions typically:

  • Rely on on-device models with limited accuracy
  • Lock users into a single app or ecosystem
  • Lack awareness of speaker identity or emotional tone
  • Offer no sensitive-content tagging (PII/PHI)
  • Require complex setup
  • Provide little or no developer extensibility

The result: voice dictation exists — but it hasn’t reached its full potential.

Our Solution: SleekVoice

SleekVoice is a native macOS menu-bar application that streams your voice directly into any active application — seamlessly and instantly.

No copy-paste. No switching apps. No workflow friction.

Every spoken word is processed through Velma-2 Streaming STT, delivering:

  • Cloud-scale transcription accuracy
  • Sub-second latency
  • Real-time intelligence signals

Core User Experience

  • Instant streaming transcription

Intelligent Text Processing

  • Automatic punctuation
  • Filler-word removal
  • Clean, readable output
  • Context-aware tone adaptation (email vs. chat vs. formal document)

Voice Command Mode

  • “Make this a bullet list”
  • “Rewrite formally”
  • “Undo last sentence”
