Polishing your English accent is not about changing who you are — it’s about ensuring you’re understood clearly and expressing yourself confidently.
For ESL professionals, this kind of clarity can unlock new career opportunities , improve presentations , and make day-to-day conversations less frustrating. Fortunately, pronunciation tools have come a long way.
With just your phone and the right app, you can start building a sharper, more natural American English accent — anytime, anywhere. Below are eight of the best accent improvement apps available in 2025, ready to be downloaded:
1. BoldVoice BoldVoice is created by immigrants, for immigrants, specifically designed for non-native English speakers who want to improve their American accent without guessing what sounds “right.”
At the heart of the app are short, focused video lessons taught by Hollywood accent coaches — the same people who train actors to sound authentic on screen. These coaches explain each sound using the IPA (International Phonetic Alphabet) , paired with clear visuals and mouth diagrams, helping you break down even the trickiest combinations of vowels and consonants .
In addition to instruction, BoldVoice gives users real-time feedback on pronunciation, fluency, pitch, and word stress using smart AI technology. The app listens as you speak and shows you exactly where your sounds need adjusting. Over time, you can track your progress, set daily practice goals, and review personal feedback summaries.
It’s especially strong in teaching speech rhythm and connected speech — areas that many ESL professionals struggle with in fast, natural English .

2. Voicetube Voicetube is a video-based language learning app that helps users improve their pronunciation and listening skills by mimicking native speakers in real-world scenarios. It offers a large library of subtitled English videos — including TED Talks, movie scenes , and interviews — with built-in tools that let you slow down audio, replay tricky phrases, and record your own voice for comparison.
The app's shadowing feature is especially useful for accent training , encouraging users to repeat lines immediately after hearing them to build rhythm, intonation , and muscle memory. Vocabulary is also highlighted and explained in context, so you’re not just repeating sounds — you’re understanding what you're saying and why it’s pronounced that way.
While Voicetube is great for natural speech exposure, it lacks detailed feedback on your pronunciation accuracy. There’s no AI or coach to tell you how close you are to the target sound, which means you’ll need to self-assess or pair it with another app that offers corrective input.
Still, for learners who enjoy real-world media and want to develop a more instinctive feel for American English, Voicetube is a strong supplement to your practice routine.
3. Say It: English Pronunciation Say It: English Pronunciation is built for learners who want to focus on precision at the word level. Developed in partnership with Oxford University Press, the app includes over 35,000 model recordings voiced by native speakers. You can listen, record your own version, and view visual sound wave comparisons to see how closely your speech matches the correct pronunciation.
It’s a great tool for isolating and practicing problem words, especially if you already have a good grasp of basic sounds and want to perfect your accuracy. The built-in dictionary and phonemic spellings make it especially handy for learners who are familiar with the IPA system.
On the downside, Say It focuses only on individual words. It doesn’t include full sentences or offer context-based practice, which limits your ability to practice connected speech and rhythm. That makes it more of a pronunciation companion than a complete accent improvement app.

4. Speakometer Speakometer is a free app that helps users practice and improve their English pronunciation using AI feedback . It’s beginner-friendly and covers both American and British English . The app includes practice sessions where you repeat target words and phrases, then get an assessment of how close your pronunciation is to native speakers.
It’s especially useful for learners on a budget or those just getting started with accent training. You can also explore sounds individually through a categorized library that organizes exercises by sound groups — voiced/voiceless pairs , vowels, and consonants.
While Speakometer is a solid entry point, it doesn’t offer in-depth instruction or structured lessons like some of the more comprehensive apps. It’s best suited as a supplement or starter app, rather than a full solution for accent training.
5. Accent Training – American Accent Training – American is a straightforward app that offers repetition-based practice to help users adopt a more native-like American accent . The app provides short listening exercises featuring native English speakers, followed by opportunities to record your own voice and compare your pronunciation side by side.
One of its strengths is simplicity — no fancy tools, just direct practice with real examples. The audio recordings include both isolated words and full sentences, giving you a feel for how pronunciation shifts in context. You can also focus on stress , intonation, and natural rhythm, which are often overlooked in basic apps.
However, Accent Training – American doesn’t include coaching, interactive instruction, or real-time corrections. If you’re someone who learns best through guidance and feedback, you might find it lacking.
That said, it’s a solid pick for learners who just want regular exposure and repetition to sharpen their American accent.
6. English Pronunciation Tutor English Pronunciation Tutor is a clean, easy-to-use app that breaks down American English sounds into manageable lessons. It covers consonants, vowels, syllables, and sentence stress through audio exercises and visual cues. You can listen to native speaker models, record yourself, and compare recordings to spot differences.
What makes this app useful is its variety of sound-focused drills. Whether you’re working on confusing sounds like /l/ vs. /r/ or trying to correct your use of voiced consonants, the app provides ample repetition and review.
Take note that the free version of the app has limited access, and some of the most valuable content is locked behind a premium paywall. Also, it doesn’t include personalized feedback or AI support, so you’ll need to self-monitor your progress.
For learners who are disciplined and want structured practice, it can still be a valuable addition to their routine.
7. Forvo Forvo is a pronunciation dictionary app that crowdsources word pronunciations from native speakers around the world. You can search for virtually any word and hear how it’s said in different English accents — including American, British, Canadian, and Australian varieties. This is especially helpful for understanding regional variations or checking tricky names and terms.
It’s quick and accurate, and the recordings are usually high quality. Forvo is a favorite among learners who frequently ask, “How do you pronounce this word?”
However, it’s not an instructional app. There are no lessons, practice exercises, or correction tools — just recordings. So while it’s an excellent resource for reference and review, it doesn’t offer a full path toward accent improvement.
8. Rosetta Stone Rosetta Stone has been a leader in language learning for years, and its latest iterations include speech recognition technology that helps users improve pronunciation and fluency. The app takes an immersive approach, using images and context instead of translation to help you think in English as you learn.
Its speech recognition feature listens to your voice and prompts you to correct mistakes in real time. You’ll practice repeating words, phrases, and sentences that gradually increase in complexity, which helps develop rhythm and natural flow.
While Rosetta Stone covers pronunciation, it doesn’t go deep into the specifics of American accent training . There’s no focus on IPA, mouth positioning, or connected speech instruction — which are key components of fine-tuning an accent.
If your goal is broader English fluency, it’s a great platform. But for accent work specifically, it may feel a bit too general.
