vowel length , master tricky consonant clusters , and even visualize how your mouth should move for each sound. But not all apps are equally effective—especially if you’re looking for real results and not just flashy features.
We’ve rounded up the 10 best English phonetics apps in 2025. Whether you're trying to reduce your accent , sound more fluent, or just polish your pronunciation , this list will help you find the right tool for your needs.
1. BoldVoice If you want an app that actually changes the way you speak, BoldVoice is it.
Built by immigrants, for immigrants, BoldVoice was created specifically for non-native English speakers to go beyond just drilling sounds—it helps you perform them. You’ll get video lessons from Hollywood accent coaches (yes, the same ones who train actors for roles), paired with cutting-edge AI that listens to your speech and gives detailed feedback on your pronunciation.
What makes BoldVoice stand out is its focus on American English phonetics. The app breaks down each of the 39 sounds in the IPA chart and shows you exactly how to produce them. You’ll get mouth diagrams, real-time scoring, and daily roleplay exercises to bring your skills into the real world.
Why it works:

Try BoldVoice free for 7 days and start sounding the way you’ve always wanted to.
2. Say It: English Pronunciation Created by Oxford University Press, Say It is a polished app that lets you record yourself and compare your pronunciation with native speakers. It’s structured around dictionary entries, so it’s particularly helpful for word-level practice.
Users can see the phonetic transcription of each word, hear native pronunciation, and watch the waveform of their voice in comparison. It’s great for pinpointing minor pronunciation mistakes.
However, it’s not very interactive beyond single-word practice and doesn’t guide users through the full range of English sounds.
3. Pronuncian – English Pronounce This app specializes in American English pronunciation, with lessons covering everything from vowel length to syllable stress and voiced/voiceless pairs . It includes podcasts , practice quizzes, and explanations of why certain sounds are hard for non-native speakers.
It’s a solid option for learners who want to dive deep into theory plus practice.
The downside is that the interface feels outdated, and there’s no built-in feedback on your pronunciation—so it’s more for passive learning than interactive coaching.

4. Speakometer Speakometer uses AI to analyze your speech and score it based on native-like accuracy. It suggests which phonemes you should work on based on your speech patterns and offers visual guides for how to pronounce each sound.
It’s a handy tool for quick check-ins or targeted sound practice, especially for British and American English learners.
That said, the feedback can be inconsistent at times, and the free version is fairly limited in content.
5. English Phonetic Symbols This one’s more of a reference app than a trainer. It offers the complete International Phonetic Alphabet (IPA) with sound examples for each symbol, making it ideal for learners who want to understand exactly what each phonetic symbol represents.
It’s a strong companion tool for anyone studying phonetics academically or independently.
Still, it doesn’t offer interactive features or speech practice—just charts and recordings—so it works best alongside a more practice-oriented app.
6. English Pronunciation Tutor This app breaks English sounds into digestible lessons, complete with animated mouth diagrams and practice drills. It also includes audio comparisons and lets users practice minimal pairs —those tiny but crucial differences like “ship” vs. “sheep.”
It’s good for learners who benefit from visual explanations.
The interface, however, is a bit clunky and feels more educational than modern, which might not appeal to all users.
7. Speak While this app is primarily a conversation simulator, it does offer some focused pronunciation tools. You’ll get to speak into the app daily and receive some high-level feedback on fluency and clarity.
It’s especially useful if you're working on speaking speed and confidence in tandem with pronunciation.
However, the phonetic instruction is fairly light—it assumes you already know the basics and just need more real-time speaking practice.
8. English Pronunciation (by Study Apps) This app covers everything from vowel sounds to stress and intonation . You can listen to native examples, repeat after them, and even get some visual aids to guide your speech.
It’s straightforward, effective, and user-friendly.
That said, the feedback isn’t personalized, and some users may find the activities a bit repetitive after a while.
9. English Phonetics (by YOBIMI Learning) This app is designed around the IPA chart and provides organized lessons for consonants, vowels, diphthongs , and word stress . It’s great for reviewing phonetic theory and testing your understanding with built-in quizzes.
It’s especially helpful for self-motivated learners.
10. Phonetics Focus (by Cambridge English Online) Gamified and fun, this app offers interactive drag-and-drop activities, quizzes, and sound-matching games to help reinforce your understanding of phonetics. It’s often used by teachers, but self-learners can benefit too.
Still, it’s more of a supplement than a full-fledged pronunciation training app—think practice, not coaching.
Boost Pronunciation with the Right English Phonetics App Phonetics is often the key that unlocks true fluency—and these apps give you the tools to take your English from “good” to “natural.”
While each app on this list brings something useful to the table, only one offers a comprehensive, coach-led, feedback-rich experience designed specifically for non-native speakers looking to refine every detail of their speech.
BoldVoice stands out for its expert-led lessons, AI-powered feedback, and structured focus on every American English sound. It’s the only app on this list that helps you perform your speech—not just study it.
Try BoldVoice free for 7 days and take the first step toward speaking English with clarity and confidence.
