🚀 Major TTS Updates: Pause Control, Speed Adjustment & SRT-to-Speech

Hey Indie Hackers,

I’ve been building QuickEditVideo.com as a free, no-login tool for creators who need lightweight but powerful editing and AI audio features.

Over the past few weeks, I kept hearing the same feedback:
👉 “I need more natural pacing.”
👉 “I wish I could slow down / speed up the voice.”
👉 “Can I just feed in my subtitles and get a voiceover automatically?”

So, I rolled up my sleeves and shipped four major TTS upgrades that I think you’ll love:

🎯 1. Pause Markup for Perfect Timing

Insert [pause] anywhere in your text to add natural breaks. Great for suspense, emphasis, or just making your voiceovers sound less robotic.

Example:
Welcome to our presentation. [pause] Today we’ll cover three topics.

🔄 2. Smoother Transitions Between Pauses

I rebuilt the audio stitching pipeline. Now pauses flow naturally with intelligent fade-ins, breath simulation, and context-aware timing. No more jarring cuts.

⚡ 3. Adjustable Speech Speed

Control pacing with settings from 0.5x (slow, detailed lectures) to 1.5x (fast, energetic intros). The AI adapts intonation and clarity so it never sounds distorted.

🎬 4. Brand New: SRT-to-Speech Tool

Upload your .srt subtitle file → get a natural AI-generated voiceover that matches timing perfectly. You can export individual clips or one combined audio file.

This is huge for creators with existing video content—turn subtitles into podcasts, accessibility audio, or alternate voiceovers instantly.
