What is the most repetitive part of preparing IVR prompts?

I built IVR Hero Lite after seeing how much time small PBX prompt changes can consume: recording, editing, converting and checking the final format.

The app turns a script into a PCM 16-bit, 8 kHz mono WAV file and supports six output languages. Edge TTS is included, with optional Azure, Google Cloud and ElevenLabs integrations.

For people working with Asterisk, FreePBX, 3CX or Yeastar: which part of the prompt workflow is still the most repetitive for you, and which export presets would save the most time?
