Experience More Control with Our New “Preview Audio” and “Pause” Features
Jan 12, 2025

Delivering high-quality video content often hinges on the smallest details—like how a word is pronounced or the timing of a dramatic pause. We’re excited to introduce two new features—Preview Audio and Pause—that give you more precision and flexibility before you commit to generating a full video.
Why Preview Audio?
Preview Audio is a game-changer for anyone who wants to make sure their text-to-speech (TTS) narration sounds exactly right before using up credits to create a video. In the past, you’d jump straight from typing your script to generating the final product. While this workflow was convenient, it didn’t leave much room for fine-tuning—and if you caught a small mistake, you’d already have spent your credits. With Preview Audio, you can:
- Verify Pronunciation & Tone
Listen to the entire audio track generated from your text and ensure it matches your desired style. - Save Credits
Catching an error in the audio before rendering a video helps you avoid unnecessary spending. - Avoid Streaming Artifacts
When audio is generated on the fly to sync with the video (a “streaming pipeline”), some AI voices can exhibit slight volume inconsistencies in the beginning and end. By using Preview Audio first, you can sidestep these artifacts and produce a more polished end result.
Common Pitfalls & Text Considerations: While TTS technology has come a long way, certain complexities can still pose challenges. Keep an extra eye on:
- Specialized or Technical Terms: Medical, legal, or scientific jargon may require additional punctuation or spelling adjustments.
- Abbreviations: Ensure TTS expands or pronounces them correctly.
- Currencies & Numbers: The narrator might speak numbers in an unexpected format or gloss over currency symbols.
- Heavy Punctuation: Periods, commas, and colons can influence how TTS handles intonation and pacing.
When you notice any issues, simply revise your text, run Preview Audio again, and confirm it’s perfect before hitting “Generate Talking Video.”
Introducing the Pause Feature
Sometimes you want to slow things down for dramatic effect, emphasize a phrase, or handle tricky words with precision. Our new Pause option—accessible via the “⏱ +0.5” icon—lets you insert a short break anywhere in your script. If you need a longer break, simply include multiple pause icons in your text. This manual pause can:
- Improve Clarity: Break up lengthy sentences so the listener clearly understands each segment.
- Enhance Emphasis: Build anticipation before a key statement or comedic punchline.
- Override Default TTS Pausing: If the text-to-speech engine doesn’t pause where you want—or adds an unintended break—manually adding pauses ensures the final narration flows the way you envision.
Important Tips
Preview Audio uses a character-based quota, which resets monthly according to your subscription tier. As a general guideline, 1 minute of speech is roughly 1,000 characters:
- Free: 500 characters (~0.5 min of audio)
- Lite: 1,000 characters (~1 min of audio)
- Pro: 10,000 characters (~10 min of audio)
- Advanced: 50,000 characters (~50 min of audio)
- Ultra: 100,000 characters (~100 min of audio)
Tips for Stopwatch Feature:
- When using the stopwatch feature, each stopwatch represents a 0.5-second pause, and you can use them consecutively to create longer pauses, up to a maximum of 3 seconds.
- Reminder: Avoid using more than two consecutive pauses within a single text segment, as this may cause the AI to produce unexpected sounds or artifacts.
Use Cases & Real-World Benefits
- Marketing & Advertising
Marketers love to spark curiosity with short, impactful lines—often followed by a well-timed pause. Now you can polish your brand messaging and preview different line deliveries without wasting credits. - E-Learning & Instructional Videos
Complex terminology or acronyms are routine in educational content. Quickly preview how they’re read out, insert the right pauses, and ensure learners can comfortably follow along. - Storytelling & Narration
Dramatic voiceovers rely on precise pacing. A perfectly placed pause can convey suspense or emotional nuance—something the auto-generated pacing of TTS might not always nail on its own. - Professional Presentations
When you need to articulate a point—say, in financial reviews or corporate pitches—mispronounced names or numbers can undermine credibility. Previewing and adding pauses helps ensure a smooth, professional vocal track.
