How to Improve Speech to Text Accuracy: 10 Proven Tips
Speech recognition has improved enormously, but the difference between a clean transcript and a frustrating one is often not the model. It is the speaker. Small, repeatable choices about where you record, how you speak, and what you do after the transcript appears have a bigger effect on accuracy than any software update.
Here are ten tips that work across tools, in any language.
Before you speak: set up the environment
Tip 1: Record in a quiet place
Background noise is the most common cause of transcription errors. Recognition engines model speech, and anything that is not speech, a fan, traffic, a television, other voices, competes for the model’s attention. Move to a quieter room, close the window, and pause the podcast. On a phone, that also means holding the device away from your mouth so your breath does not create pops.
Tip 2: Keep the microphone consistent
The same words sound different from ten centimeters away and fifty centimeters away. Keep the phone or microphone at a consistent distance while you speak, and do not wander around the room mid-dictation. Veena records 16 kHz mono audio, which is a clean signal for speech, but a moving source degrades any signal.
How you speak matters
Tip 3: Speak at a steady pace
Rushing invites errors; speaking like a robot invites them too. Aim for a natural, even pace, the one you use when explaining something carefully to a colleague. There is a sweet spot where the recognizer has time to work without you sounding stilted. Slowing down slightly on names and numbers pays off immediately.
Tip 4: Avoid code-switching
Mixing two languages in one sentence is a problem for recognition engines, because each language model competes for the same audio. A sentence that jumps between languages is a challenge for any recognizer. Veena’s engine covers all 22 scheduled languages of India, and each language has its own vocabulary and decoding tuned for it, so choose one language per recording and stick to it. You can always dictate different recordings in different languages: here is Hindi speech to text and here is Tamil speech to text.
Tip 5: Use punctuation words
Say “full stop”, “comma”, “question mark”, and “new line” out loud instead of expecting the engine to guess sentence boundaries. It takes a little practice and saves a lot of editing. Many tools, including Veena, transcribe these words into punctuation, and the habit alone makes transcripts far more readable.
Tip 6: Enunciate names and numbers
Speech recognizers guess unfamiliar words from context, and they guess wrong more often than they guess right. When you dictate a name, a code, or a dosage, slow down and pronounce each syllable. If the tool keeps getting a word wrong, spell it out for that segment and fix it in the editable transcript.
Get the model on your side
Tip 7: Choose the right model for your device
More capable models are more accurate and slower; lighter models are faster and less accurate. On the desktop app, Veena offers downloadable models with accuracy and speed trade-offs, so a laptop can run a lighter model for quick notes and a larger one for long documents. Match the model to the task instead of suffering with a default.
Tip 8: Stay inside one language per session
The language setting is not decoration. If the app is set to Bengali and you dictate English, expect the transcript to fight you. Pick the language you are actually speaking, and if you switch languages mid-dictation, start a new recording rather than continuing the old one.
After the transcript appears
Tip 9: Edit the hot spots, not the whole text
You do not need to proofread a transcript like a document. Fix the hot spots: proper nouns, numbers, technical terms, and anything you will be judged on. The transcript appears in an editable text box in Veena, so corrections take seconds, not minutes. On the desktop app you can also enable filler-word removal so “um” and “uh” never reach the text at all.
Tip 10: Learn from repeated errors
If the same word is wrong every time, that is data, not bad luck. Either the word is unusual, or your pronunciation of it is. On the desktop app, custom-word correction lets you teach Veena the words you use often, which fixes the repeated error at the source. When a word is not worth teaching, change how you say it: clearer syllables usually do the trick.
What accuracy you can expect
It would be convenient to quote a percentage here, but honest accuracy claims are harder than that. Accuracy depends on the language, the model, the microphone, and your delivery, and anyone quoting a single number is oversimplifying. What is predictable: clear speech, a quiet room, and the right model produce markedly cleaner transcripts than rushed dictation on a noisy bus. The engine in Veena is built on IndicConformer, a multilingual model from AI4Bharat, with a dedicated vocabulary per language, which is why the tips above work well with it.
The bottom line
Accuracy is a habit, not a setting. Quiet the room, pace yourself, speak one language per recording, say your punctuation, and spend twenty seconds fixing hot spots. Do that, and dictation stops being a gamble and becomes a reliable way to write.
