Hey everyone,

OpenVox for Mac **v2.5.0** is now available.

The biggest addition in this update is something I’ve wanted to build for longer generations: **local output validation**.

When generating audiobooks, narrations, or large batches, even a good TTS model can occasionally skip a word, mispronounce something, repeat text, or generate something different from the original script.

Until now, finding those mistakes meant manually listening through the entire output.

With **Validate Output**, OpenVox can now check the generated speech for you.

# 🔍 Validate Output

After generating speech, OpenVox can locally transcribe the generated audio and compare it against your original text.

It then highlights sections that may need your attention.

You can:

* See potentially incorrect sections with **timestamps and text-match scores**
* Compare the original text with what OpenVox detected in the generated audio
* Listen directly to the flagged section
* Edit the expected pronunciation or text when needed
* Select only the problematic sections you want to regenerate
* Preview the regenerated audio before making any changes
* Use **Confirm & Update** to replace only those sections in the final output

The matching system is also designed to avoid unnecessary warnings. It intelligently ignores harmless differences involving punctuation, spacing, apostrophes, and joined words.

Everything happens **locally on your Mac**.

# 🇯🇵 Better Japanese & CJK Generation

This update also includes several improvements for Japanese and other CJK languages.

Text chunking is now safer for languages where sentence and word boundaries behave differently from English, helping prevent problematic splits during longer generations.

I also fixed a **Supertonic crash affecting CJK-language generation**.

# 🎙️ Voice Clone Improvements

Voice Clone can now accept:

* MP4
* MOV

OpenVox automatically extracts the audio from the video, so you no longer need to convert the file separately before using it as a voice reference.

# 🎛️ More Precise Speed Controls

Speed knobs now support **0.01x adjustments**.

This makes it much easier to fine-tune pacing when you need something between values like 0.95x, 0.96x, 0.97x, etc.

# ⚡ Memory Improvements

I’ve also improved memory handling when switching between speech-generation and transcription models.

This is particularly useful now that workflows like Validate Output can involve both TTS and transcription models during the same session.

# OpenVox 2.5.0 includes:

* Local transcription-based **Validate Output**
* Timestamped validation results with text-match scores
* Selective regeneration of incorrect sections
* Preview before replacing regenerated audio
* Smarter text matching
* Improved Japanese and CJK text chunking
* Fixed Supertonic crashes with CJK languages
* MP4 and MOV support in Voice Clone
* Precise **0.01x** speed adjustments
* Improved model memory management

As always, OpenVox keeps the speech generation, transcription, validation, and processing on your Mac.

If you try the new **Validate Output** workflow, I’d especially like to hear how well it catches issues in your longer audiobook and batch generations.
