How to check your pronunciation online for free

To check your pronunciation online for free, read a short sentence aloud into a checker that records and scores your own voice, then look for the one sound it flags most often. Fix that sound, record the same sentence again, and compare.

Two kinds of free tools, and only one checks you

Search for a pronunciation checker and you get two very different things.

The first kind plays you a model. You type a word, and a dictionary or text-to-speech voice says it. That is useful for hearing the target, but it measures nothing about your speech. You still don’t know what you sound like.

The second kind listens. You read a sentence into your microphone, and the tool compares your recording with the text. It gives you a score for each word and often for each sound. This is the kind you want when you search “check my pronunciation.”

A quick way to tell them apart: if the tool never asks for your microphone, it is not checking you.

Set up for a fair score

A checker can only judge the audio it gets. Before you record:

• Find a quiet room. A fan or a TV in the background can lower your score.
• Hold your phone or microphone about 15 to 30 cm from your mouth.
• Read at your normal speed. Don’t slow down or over-pronounce on purpose. You want to check how you really talk.
• Read the whole sentence. Skipped words count against you.

One more thing to know: the checker scores what you said, not what you meant to say. If you misread “walked” as “worked,” it will mark the word you actually produced. Read the sentence silently once before you record.

Test the checker in one minute

Not every free checker hears small differences. Before you trust one, give it a test it should not pass.

Choose a minimal pair: two words that differ in only one sound. Type the first word as your text, then say the second word on purpose. If the checker gives you a high score, it isn’t listening closely enough to help you. A good one will flag the sound you changed.

The /l/ and /r/ pair works well for this test, because many learners mix them up and the difference is easy to make on purpose.

Try it now: set the text to “light” and say “right.” Then set it to “right” and say it properly. You should see a clear gap between the two scores. If you do, the checker is worth your time.

How to read your results

Most checkers give you several numbers. The names change from tool to tool, but they usually measure something like this:

• Accuracy: how close each sound is to the reference accent.
• Fluency: how smoothly you speak, with natural pauses.
• Completeness: whether you said every word in the text.
• Sound (phoneme) scores: a score for each individual sound in each word.

The overall score is the least useful number. It goes up and down with your energy, your microphone and the sentence you picked. The sound scores are where the real information is.

Here is what to look for. Read three or four different sentences, then scan the flagged sounds. One wrong sound in one word could be a slip. The same sound flagged in four words is a habit. That habit is what you practice.

For example, say you read these and get these flags:

• “I think it’s three o’clock.” (/θ/ flagged twice)
• “We walked to the park.” (/ɔː/ flagged)
• “Thanks for the gift.” (/θ/ flagged)

The vowel in “walked” might be a one-off. The /θ/ sound shows up three times, so that’s your target this week.

The check, fix, recheck loop

Checking alone won’t change your pronunciation. Running the same short loop every time you practice will:

1. Check. Read three short sentences and note the sound that is flagged most.
2. Listen. Play a model of one flagged word with a dictionary or text-to-speech voice. Listen three times before you speak.
3. Build up. Say the sound alone, then the word, then a short phrase, then the full sentence. Go slowly at first.
4. Recheck. Record the exact same sentence again. Same text, same distance from the microphone, so you are comparing like with like.

If you’d like a free checker to run this loop with, NativeSpeech’s pronunciation checker needs no sign-up: record a short clip and it marks each sound, so you can see which ones to fix.

Here is a sentence packed with /l/ and /r/ to use for your first loop.

Read it, check it, fix the weakest sound and read it again. Then try these phrases as single units, without pausing inside them:

When the score looks wrong

Sometimes a checker marks a word you are sure you said well. Before you change how you speak, check these things:

• The recording. Play it back. Is there noise, a cut-off start, or a quiet voice?
• The text. Did you say exactly what is written, including small words like “the” and “a”?
• The accent setting. There is no single correct English. A British “can’t” may lose points if the checker is set to American English. Choose the accent you want to sound like.
• One bad take. Record the sentence twice more. If the flag disappears, it was a slip, not a habit.

If the same sound keeps getting flagged after all that, trust the pattern.

A free check with no checker at all

You can also check yourself with just your phone. Record yourself saying a word, then play a dictionary recording of the same word, then play yours again right after. Listen for one thing at a time: first the vowel, then the last consonant, then which syllable is stronger. It’s slower than an AI checker, but it trains your ear, and a better ear makes every other kind of practice work better.
