Script to Voice Generator - Google TTS

Script to Voice Generator - Google TTS

Turn author scripts into fully voiced audio files with Google Cloud TTS (Chirp 3 HD), per-character effects, and smart merging.

## Description

Script to Voice Generator converts formatted `.txt` or `.md` script files written by you into fully voiced audio files using **Google Cloud Text-to-Speech** — over 2,000 voices across 50+ languages, with Chirp 3 HD as the standout: expressive, natural, and genuinely impressive output that holds up to real scrutiny.

Each speaker in your script gets their own voice, pitch, speed, and audio effects. Assign Radio, Reverb, Distortion, Telephone, Robot Voice, Cheap Mic, Underwater, Megaphone, Worn Tape, Intercom, Alien Voice, or Cave effects per character at Off / Mild / Medium / Strong levels. Two bonus toggles — FMSU (brutal digital corruption) and Reverse — round out the toolkit. Combine effects freely for distinct character identities.

With 2,000+ voices to choose from — and per-character speed, pitch shift, and effect chains on top — the number of distinct-sounding characters you can build is effectively unlimited.

Google Cloud TTS provides a generous **1,000,000 free characters per month** for Chirp 3 HD and other premium voices. For most personal and indie projects, that's plenty enough to voice practically anything you need to.

As an estimate, for those 1 million free characters per month, you can generate roughly 18 to 22 hours of audio content - for free. The exact duration depends on the average word length and the speaking rate of the voice.

**The generator produces:**
- Individual audio per each spoken line — clean (TTS only) and effects-processed versions
- All (effects-enabled) clips merged into a fully edited and smartly paced audio file, not normalized (true audio, better for media/games)
- All (effects-enabled) clips merged into a fully edited and smartly paced audio file, loudness normalized (even audio, better for podcasts)
- Reference .txt file with filenames, line numbers, and spoken content for every clip
(Output format is MP3 by default; switch to OGG Opus in Settings for better quality at the same file size)

**Features:**
- 2,000+ Google Cloud TTS voices (Chirp 3 HD, Neural2, WaveNet, Standard — English and multilingual)
- Per-character voice, pitch, speed, volume, and audio effects
- 12 audio effects with 4 levels each — combinable
- 2 bonus toggles: FMSU (brutal corruption) and Reverse

- Inner thoughts filter (Whisper, Dreamlike, Dissociated presets)
- Sound effect events (play/stop/loop) placed in the merge timeline
- Smart merged audio with configurable punctuation-based pause timing

- Output format selector: MP3 or OGG Opus (same free tier quota, better quality)
