Pronunciation feedback designed for the Spanish mouth.
IPA-level phonetic analysis trained on the exact errors Spanish speakers make in English — th/d substitution, vowel reduction, lexical stress, and false cognates that change meaning.
It's not your English. It's six sounds.
Most Spanish speakers don't have a vocabulary problem — they have a phonetics problem. Six recurring patterns (th/d, ʃ/tʃ, vowel reduction, primary stress, voicing, /h/) account for ~80% of the moments where listeners flag your English as non-native. Generic apps don't isolate them. Tutors can't catch them at the speed you speak.
SpeakBetter.AI was built to find them in milliseconds.
From sound to fix in under a second.
Speak any phrase
Read a medical sentence or improvise — clinical, conversational, or conference register.
Phonetic analysis
Whisper-large-v3 + a custom Spanish-medical phoneme model breaks your speech into IPA tokens.
Error isolation
Each mispronunciation is flagged at the phoneme — not just the word — with the specific Spanish-interference rule that caused it.
Targeted drill
A 30-second drill tuned to that exact phoneme pattern, queued for your next session.
Tuned to the patterns Spanish speakers actually struggle with.
Phoneme-by-phoneme transcription so you can see exactly which sound deviated.
Your waveform and pitch contour compared side-by-side with a native medical English speaker.
Hundreds of documented Spanish-to-English interference patterns — th/d, ʃ/tʃ, vowel hiatus.
Catches constipation/constipación, embarrassed/embarazada, intoxicated/intoxicado before they reach a patient.
ar·RHYTH·mi·a, not ar·rhyth·MI·a. Stress errors are flagged with the corrected pattern visible.
Linking, elision, weak forms — the rules that turn book English into spoken English.
A visual map of which sounds you nail and which need work, refreshed every session.
Hear yourself, hear the native, then re-record. Three loops per drill, fully accessible.
Track accuracy per phoneme over weeks. See th-substitution drop from 38% to under 5%.
