What is IISC?
Listen to Text Instead of Reading It
IISC uses Text to Speech technology to synthesize natural‑sounding speech from ordinary text. Copy text to the clipboard or import from a file — IISC reads it back to you instantly. It also converts text into MP3 or WAV audio files so you can listen later on any device.
Create audio files from your email, news articles, eBooks — anything you want. Download to your portable MP3 player and go. Now new version 1.30 released with more powerful features including Control Tags, Key To Speech, Pronunciation Manager, and Alarm & Reminders.
Key Features
Everything You Need
Configurable Clipboard Options
You decide exactly how IISC behaves whenever your computer's clipboard changes — automatic reading, confirmation prompt, or silent.
Alarm & Reminders
Like an alarm clock, IISC announces the time at every interval you choose. It also maintains a reminders list so you never miss an important task.
Configurable Global Hotkeys
Define favourite global hotkeys to control IISC even while working in another application — ideal for visually impaired users.
Optional MP3 Quality Control
Output Sample Frequencies and Bitrates options let you balance audio quality versus file size — from 8 kbps voice clips to 320 kbps studio quality.
Powerful Command Lines
Advanced users can script any operation — text to speech, text to WAV, text to MP3, WAV to MP3, MP3 to WAV — all from the command line.
Multiple Languages & Engines
Supports English, Spanish, British English, Dutch, French, German, Italian, Portuguese and more via downloadable voice engines.
Multiple Output Modes
Send synthesized speech to your speakers in real time, or save it directly to WAV or MP3 audio files for use on any device.
Plain Text File Support
Drag and drop .txt files directly from Windows Explorer into IISC, or right‑click any .txt file to convert it to MP3 via the context menu.
Pronunciation Manager
Edit the phonetics of mispronounced words and load or unload personal exception dictionaries to get exactly the pronunciation you need.
