Voice mode drops recording mid-sentence and moves cursor backwards

Description

Voice mode (/voice) intermittently stops recording mid-sentence and repositions the cursor several characters backwards. The user has to press the forward arrow key multiple times to reach the end of the input, then re-record. This happens frequently but not every time.

Impact

Input arrives fragmented. Sentences are broken mid-word. The model receives garbled prompts and has to guess intent.

Steps to reproduce

1. Start Claude Code session
2. Use /voice or enable voice mode
3. Speak a full sentence (10+ words)
4. Observe that recording stops before the sentence is complete
5. Cursor is positioned several characters before the end of the transcribed text
6. Must arrow-forward to end and re-record the rest

Environment

• Platform: Linux (Pop!_OS, kernel 6.17.9)
• Claude Code: latest as of 2026-04-01
• Voice mode enabled via settings.json ("voiceEnabled": true)
• Occurs during extended sessions (2+ hours)
