10 Tips for Better Accuracy
Getting the most out of TalkWriter comes down to good microphone habits, clear speech, and the right settings. Here are ten tips ranked by impact.
Why Accuracy Matters
Even a 5% improvement in speech recognition accuracy dramatically changes your experience. At 90% accuracy, you correct roughly one word per sentence. At 95%, you correct one word every two sentences. At 98%, you barely correct anything. The tips below are the difference between "dictation that needs editing" and "dictation you can send as-is."
The Tips
1. Use an External Microphone
Impact: ⭐⭐⭐⭐⭐ Critical
Your Mac's built-in microphone works, but a dedicated USB microphone or headset dramatically improves accuracy. External mics capture clearer audio with less background noise.
| Microphone Type | Accuracy Improvement |
|---|---|
| Built-in Mac mic | Baseline |
| USB headset | +20-30% fewer errors |
| USB condenser mic | +30-40% fewer errors |
See Microphone Best Practices for detailed recommendations.
2. Reduce Background Noise
Impact: ⭐⭐⭐⭐⭐ Critical
Background noise is the number one cause of dictation errors. Close windows, turn off fans, and move away from noisy environments.
If you cannot control your environment, use a headset with a boom microphone. The close-talk design rejects most ambient noise.
3. Keep Consistent Distance from Your Microphone
Impact: ⭐⭐⭐⭐ High
Stay 6-12 inches from an external microphone, or 1-2 inches from a headset mic. Moving closer or farther mid-dictation causes volume fluctuations that confuse the speech engine.
4. Speak at Your Natural Pace
Impact: ⭐⭐⭐⭐ High
Do not slow down or over-enunciate. TalkWriter's speech engine is trained on natural conversational speech. Speaking unnaturally can actually reduce accuracy.
5. Use Push-to-Talk Mode
Impact: ⭐⭐⭐⭐ High
PTT mode uses silent real-time streaming, which provides maximum accuracy. It also ensures TalkWriter only records when you intend it to, eliminating noise from pauses.
6. Set the Correct Language
Impact: ⭐⭐⭐⭐ High
Manually set your language in Settings rather than relying on auto-detect. When TalkWriter knows which language to expect, the speech engine is significantly more accurate.
7. Add Custom Words to Your Dictionary
Impact: ⭐⭐⭐ Medium
Technical terms, product names, people's names, and jargon are often misheard. Add them to your TalkWriter Dictionary so the AI recognizes them.
Examples of words to add:
- Company names: "Acme Corp", "TalkWriter"
- Technical terms: "Kubernetes", "PostgreSQL", "API"
- People's names: "Sundar", "Reshma", "Wojciech"
8. Dictate Complete Thoughts
Impact: ⭐⭐⭐ Medium
Speak in full sentences rather than isolated words or fragments. The AI model uses context to improve accuracy. A complete sentence gives it more context to work with.
| Less Accurate | More Accurate |
|---|---|
| "Meeting... tomorrow... 3 PM" | "The meeting is scheduled for tomorrow at 3 PM." |
| "Bug... login... fix" | "There is a bug in the login flow that needs to be fixed." |
9. Pause Between Separate Ideas
Impact: ⭐⭐ Moderate
When switching topics or starting a new paragraph, pause briefly (1-2 seconds). This helps TalkWriter's AI understand sentence boundaries and apply better formatting.
10. Keep AI Polish Enabled
Impact: ⭐⭐ Moderate
AI Polish catches errors that slip through speech recognition. It fixes misheard words based on context, adds proper punctuation, and cleans up grammar. Turning it off means you get the raw, unedited transcription.

Frequently Asked Questions
I followed all the tips but accuracy is still poor. What else can I try? Check your microphone input level in System Settings > Sound > Input. Make sure the level meter moves when you speak. If it barely registers, your mic may be muted or misconfigured.
Does accuracy improve over time? TalkWriter does not adapt to your voice over time. However, adding words to your Dictionary improves recognition of your specific vocabulary.
Is Push-to-Talk more accurate than Live mode? Slightly. PTT uses silent real-time streaming which can improve accuracy, particularly in noisy environments.
Practical Example: Maximum Accuracy Setup
Scenario: You are a medical professional dictating patient notes and need the highest possible accuracy.
- Microphone: Use a USB headset with a boom mic (e.g., Jabra Evolve2). Position the mic 1-2 inches from your mouth.
- Environment: Close your office door. Turn off any fans or background noise.
- Language: Set speech language to English (US) manually -- do not use auto-detect.
- Mode: Use PTT mode for maximum accuracy via silent streaming.
- Dictionary: Add all medical terms you use regularly (drug names, procedure names, abbreviations).
- AI Polish: Keep it on -- it catches context-based errors the speech engine misses.
- Speak naturally: Full sentences with medical context ("The patient presents with bilateral lower extremity edema") are recognized better than fragments ("edema... bilateral... lower").
With this setup, you can expect 95%+ accuracy on general speech and 90%+ on specialized medical terms.
The single highest-impact change you can make is switching from your Mac's built-in microphone to any USB headset. This alone can reduce errors by 20-30%, even without changing anything else.
