Google Slides TTS Setup
Google Slides, on the other hand, requires alternative approaches to add TTS functionality.
| Method | Setup Process | Best For |
|---|---|---|
| Separate Audio | Upload MP3/WAV to Drive, then insert via Audio | Pre-recorded presentations |
| Screen Recording | Record narration over slides and insert as video | Live demonstrations |
| Live Recording | Use Slideshow > Record Slideshow | Interactive sessions |
For the separate audio method, write your narration script, record it as an MP3 or WAV file, and insert it into your slides using Insert > Audio. Afterward, adjust slide timing to match the narration.
Audio-Slide Timing
Synchronizing TTS narration with your slides is crucial for a smooth presentation. Use these tools for better timing control:
PowerPoint Timing Controls:
- Record slide timings automatically while narrating.
- Manually adjust timings for precise synchronization.
- Trim recorded audio segments for better alignment .
Google Slides Audio Settings:
- Set audio to play automatically or on click.
- Hide the audio icon during presentation mode for a clean look.
- Ensure audio stops when transitioning between slides .
For a polished and professional touch, explore advanced TTS tools like ElevenLabs or Animaker Voice. These platforms offer enhanced voice modulation and timing features, making them ideal for academic presentations .
Guidelines For TTS Academic Presentations
Creating academic presentations with TTS (Text-to-Speech) technology requires careful planning. From script writing to voice settings, every detail matters to ensure clarity and engagement.
Writing for TTS
When preparing your script, keep sentences short and easy to follow. Here are some tips to guide you:
| Writing Element | Best Practice | Why It Matters |
|---|---|---|
| Sentence Length | Write in short sentences | Avoids awkward pauses in delivery |
| Terminology | Stick to consistent terms | Improves understanding |
| Language Style | Keep it simple and jargon-free | Ensures smooth TTS narration |
| Visual Support | Use visuals to complement text | Lets visuals handle emotional context |
Skip emotional phrases or casual expressions – use visuals to set the tone instead. Combining TTS with live narration can also help create a dynamic presentation.
Combining TTS and Speaker Voice
Mixing TTS with live narration can enhance your presentation’s flow and keep your audience engaged. Here’s how to do it:
- Strategic Voice Use: Rely on TTS for technical details, data-heavy sections, or complex explanations. This ensures consistency and frees you up to connect with your audience during live segments.
- Smooth Transitions: Clearly mark where TTS ends and live narration begins in your notes. This avoids awkward overlaps and keeps the flow seamless.
Balancing both elements ensures the audience stays focused and engaged.
Adjusting Voice Settings
Fine-tuning TTS voice settings is essential for clear and engaging delivery. Adjust these key parameters:
| Parameter | Recommendation | Ideal For |
|---|---|---|
| Speech Rate | Slow down for complex information | Technical or detailed sections |
| Pitch | Use a lower pitch for authority | Setting the tone and mood |
| Volume | Ensure it’s loud enough for the room or recording | Large spaces or online presentations |
| Pauses | Add pauses between key points | Giving the audience time to process |
For technical sections, slower pacing and intentional pauses can make a big difference. Fine-tuning these settings ensures your message is both clear and impactful.
Common TTS Challenges In Academic Presentations
Academic presentations often encounter specific text-to-speech (TTS) challenges. Tackling these issues is key to delivering a smooth and engaging presentation. Below, we outline common challenges and practical solutions.
Complex Terms and Math
Technical terms and mathematical expressions can be tricky for TTS systems. Here’s how to handle them effectively:
| Challenge | Solution | Implementation |
|---|---|---|
| Scientific Terms | Use phonetic spellings in backticks | Write “CRISPR” as “C-R-I-S-P-R“ |
| Mathematical Symbols | Spell out symbols | Say ‘∑’ as ‘sum from’ |
| Acronyms | Enclose acronyms in backticks | Use “N-L-P” instead of “NLP” |
Narakeet offers precise control over specialized vocabulary pronunciation .
Pronunciation Fixes
Once you’ve tackled complex terms, focus on improving pronunciation. Advances in natural language processing (NLP) have made TTS systems better at handling this.
To refine pronunciation:
- Train your TTS system with field-specific terminology.
- Use prosodic features to add emphasis naturally.
- Make context-aware adjustments for technical terms.
