Why Accuracy Matters
Even small accuracy improvements have massive impact. Going from 90% to 95% accuracy means half as many errors to fix—and that time savings adds up fast.
Low Accuracy
10 errors per 100 words. A 1,000-word document needs 100 corrections. Editing takes longer than dictating.
Good Accuracy
5 errors per 100 words. A 1,000-word document needs 50 corrections. Manageable editing load.
Excellent Accuracy
2 errors per 100 words. A 1,000-word document needs only 20 corrections. Nearly publish-ready.

Tip: Keep the tab focused, use a good microphone, and speak clearly. Accuracy depends on your browser and device.
Microphone Setup & Positioning
Your microphone is the most important factor in accuracy. Garbage in, garbage out—even the best AI can't transcribe muffled or distorted audio.
Distance: 6-12 Inches from Mouth
Position your mic about a hand's width from your mouth. Too close causes distortion and popping. Too far picks up room noise and reduces clarity.
Angle: Off-Axis to Reduce Plosives
Point the mic slightly to the side of your mouth, not directly at it. This reduces "popping" sounds from P, B, and T consonants without losing clarity.
Consistency: Same Position Every Time
Moving the mic mid-session changes audio characteristics. Use a mic stand or headset to maintain consistent positioning throughout your dictation.
Use a Pop Filter for Condenser Mics
If using a condenser microphone, a pop filter ($10-20) dramatically reduces plosive sounds that confuse speech recognition. Essential for studio-quality accuracy.
Optimizing Your Environment
Your physical environment significantly impacts recognition accuracy. Here's how to create the ideal dictation space.
Reduce Background Noise
Close windows, turn off fans and AC units, silence phone notifications. Even quiet background sounds force the AI to distinguish your voice from noise.
Minimize Echo
Hard surfaces reflect sound. Add rugs, curtains, or acoustic panels. A closet full of clothes is actually an excellent makeshift recording booth.
Consistent Volume Level
Sudden loud sounds (doors, notifications) can throw off recognition. Create a quiet, consistent acoustic environment for your dictation sessions.
Consider Time of Day
Early morning or late evening often have less ambient noise (traffic, neighbors, construction). Schedule important dictation during quiet hours.
Speaking Techniques for Clarity
How you speak matters as much as your equipment. These techniques train you to be more "machine-readable."
Slow Down Slightly
You don't need to speak unnaturally slowly, but conscious pacing helps. Aim for 120-130 words per minute instead of rapid-fire 150+. Clarity beats speed.
Enunciate Clearly
Pronounce consonants distinctly, especially at the end of words. "Going" vs "goin'" makes a difference. Crisp articulation prevents most errors.
Pause Between Sentences
Brief pauses give the AI clear sentence boundaries. This improves punctuation accuracy and reduces run-on transcription errors.
Maintain Consistent Volume
Don't trail off at sentence ends or mumble. Keep your volume steady throughout. Fading volume causes recognition to guess at endings.
Fixing Common Recognition Errors
Certain word types cause predictable problems. Here's how to handle them.
Homophones: "there/their/they're"
Solution: Context usually handles this, but you can specify: "their, T-H-E-I-R" when precision matters. Or just fix during editing—homophones are fast to correct.
Names and Proper Nouns
Solution: Spell unusual names: "John, J-O-H-N" or add to custom vocabulary if your tool supports it. For repeated names, establish spelling once and the AI often learns.
Technical Terms and Jargon
Solution: Speak technical words slowly and clearly. Many tools let you add custom vocabulary. For very obscure terms, spelling out may be fastest.
Numbers and Dates
Solution: Say "twenty twenty-six" vs "2026" depending on desired output. "December fifth" vs "12/5". Be explicit about format to avoid ambiguity.
Similar-Sounding Words
Solution: "Effect" vs "affect"—slow down and over-enunciate the distinguishing sounds. If a word keeps mis-recognizing, try a synonym.
Training Your Voice Recognition
Some voice typing systems learn from your corrections. Here's how to train them effectively.
Correct Errors Consistently
When you fix a recurring error, the system may learn the correct association. Be patient—learning happens over many corrections.
Use Custom Vocabulary Features
Many tools let you add names, jargon, and unusual words to a personal dictionary. Take time to add words you use frequently.
Complete Voice Training (If Available)
Some systems offer voice enrollment where you read sample text. This calibrates the system to your specific voice patterns. Worth the 10-15 minute investment.
Be Consistent in Your Speech
Speaking the same way each session helps the system learn your patterns. Dramatic changes in speaking style reset learned adaptations.
Advanced Accuracy Techniques
For power users seeking maximum accuracy, these advanced techniques can make a difference.
Warm Up Your Voice
Spend 2-3 minutes speaking before important dictation. Read aloud or hum. A warmed-up voice is clearer and more consistent than a cold start.
Stay Hydrated
Dry vocal cords produce raspier audio. Keep water nearby and sip regularly during long sessions. Avoid excessive caffeine which can dry your throat.
Monitor Input Levels
If your system shows input volume, aim for levels in the green zone—not peaking into red (distortion) or barely registering (too quiet).
Use Shorter Sessions
Voice fatigue sets in after 45-60 minutes. Take breaks to maintain vocal clarity. Tired voices slur and trail off, reducing accuracy.
Test Different Browsers
For web-based tools, Chrome often has the best speech recognition. Safari and Firefox use different engines with different accuracy profiles.
Consider Your Accent
Some systems handle certain accents better. If accuracy is low, try selecting a regional language variant that matches your accent more closely.
Frequently Asked Questions
What accuracy should I expect?
With good equipment and technique, 95-98% accuracy is achievable for clear speakers in quiet environments. Accented speech, technical jargon, or noisy environments may see 90-95%. Below 90% usually indicates equipment or environment issues.
Why does accuracy vary day to day?
Many factors affect daily accuracy: your voice condition (tired, congested), background noise levels, microphone positioning, even internet connection quality for cloud-based recognition. Consistency in setup helps minimize variation.
Does a better microphone really help?
Yes, significantly. Upgrading from laptop mic to a decent USB headset often improves accuracy by 5-10%. Further upgrades to quality condenser mics yield diminishing but real returns. The mic is your single best accuracy investment.
How do I handle words it always gets wrong?
Add them to custom vocabulary if available. Otherwise, develop workarounds: use a synonym, spell it out, or accept fixing it in editing. Some words are just acoustically ambiguous.
Is accuracy better with premium services?
Often, yes. Premium services may use more advanced AI models, offer better noise cancellation, support custom vocabulary training, and provide specialized models for specific domains (medical, legal). Free tools are good but paid tools are often better.
