Drill sentences start easy (isolated sounds) and progress to complex sentences as your score improves. Score drops trigger automatic regression.
Score History
Every session is logged. See your pronunciation score trend over weeks and months in a clear chart on the Progress tab.
Vocabulary Builder
Words you mispronounce are automatically saved to your vocabulary deck with a phonetic guide so you can review them later.
Frequently Asked Questions
What makes SpeakCoach the best AI English tutor?
SpeakCoach analyses the audio waveform of your speech — not just a transcript. It scores 16 different phonological categories, builds a personal weakness profile, and adapts drill difficulty as you improve. Most apps only check if you said the right words; SpeakCoach checks how you said them.
How does AI pronunciation coaching work?
SpeakCoach uses Azure Cognitive Services pronunciation assessment combined with Gemini AI analysis. It compares your speech to reference pronunciation at the phoneme level, scores each sound, and identifies patterns across sessions to build a personalised improvement plan.
Which English sounds does SpeakCoach target?
SpeakCoach tracks 16 sound categories: V/W confusion, S/SH sounds, T/TH sounds, D/DH sounds, vowel length, word stress, retroflex consonants, schwa deletion, intonation, consonant clusters, linking, epenthesis, devoicing, aspiration, silent letters, and diphthongs.
Can beginners use SpeakCoach?
Yes. The onboarding flow assesses your current level and sets drill difficulty accordingly. Beginners get easier sentences with isolated sounds. The difficulty adjusts automatically as you improve.
Does SpeakCoach work without internet?
SpeakCoach requires an internet connection for AI analysis since audio is processed on secure servers. However, the Android app caches your progress data so you can review your history and drills offline.
