TTY WAV Reader 1.0

TTY WAV Reader by Cisco Systems, Inc. is a specialized utility for decoding and reviewing TTY/TDD (Baudot) text embedded in WAV audio recordings. It helps voice, contact center, and public safety teams verify accessibility, troubleshoot call flows, and document TTY content carried over PSTN and VoIP infrastructures.

Key capabilities:

• Decodes standard U.S. TTY Baudot (45.45 baud, 5-bit) from mono or stereo WAV files at common sample rates
• Automatically detects 1400/1800 Hz mark/space FSK and reconstructs text with letter/figure shifts
• Provides time‑aligned transcripts with playback controls and channel selection (left/right)
• Highlights low‑confidence or garbled characters and common TTY abbreviations (e.g., GA, SK)
• Exports transcripts and timestamps to TXT or CSV; optional annotated WAV saving
• Supports batch processing and basic signal statistics to aid troubleshooting

Typical use cases:

• Validating TTY transport through SBCs, gateways, recorders, and call centers
• Quality assurance and documentation for PSAP and emergency services recordings
• Accessibility compliance testing and regression checks across network changes

System notes:

• Accepts standard PCM WAV inputs (commonly 8–48 kHz)
• Lightweight desktop utility; suitable for Windows environments

With accurate decoding, clear visualization, and convenient export options, TTY WAV Reader streamlines TTY analysis and documentation for operational and compliance needs.
