Lucy OS1 gives you real-time AI pronunciation coaching that identifies exactly which Spanish sounds you are getting wrong, so you fix the right things rather than practicing sounds you already produce correctly. For English speakers, the trilled R (vibrante) is almost always the first target, but the five pure Spanish vowels, the merged b/v sound, and the rhythm of syllable-timed sentences all contribute to a non-native accent. Lucy OS1 listens at the phoneme level and gives you a correction model to repeat immediately, which is how pronunciation changes fastest. Most learners see clear improvement in their hardest sounds within two to three weeks of daily focused sessions.
WHAT TO LOOK FOR
Trilled R Training
Lucy OS1 isolates and drills the Spanish vibrante, the trilled R produced by fluttering the tongue tip against the ridge behind your upper front teeth, which is the single hardest sound for most English and East Asian speakers. You hear a model, produce the sound, and get immediate feedback on whether you hit the correct vibration.
Vowel Accuracy Drills
Spanish has five pure, short vowels that are more consistent than English vowels, and mispronouncing them affects how natural your overall speech sounds. Lucy OS1 trains each vowel position until your production matches the native speaker model you are targeting.
Accent Family Selection
You can practice Peninsular Spanish pronunciation, which includes the distinct th-sound (ceceo) for c and z, or Latin American pronunciation, which uses seseo and does not distinguish those sounds. Choosing the right variety for your goals from the start means every session builds toward the right target.
TL;DR:Lucy OS1 catches pronunciation errors at the phoneme level and tells you exactly which sounds are off, including the trilled R that most language apps skip entirely. Specific phoneme-level feedback cuts the time to accurate pronunciation significantly compared to general conversation practice alone.

Lucy OS1 identifies the specific part of each word where your pronunciation diverges from the target, rather than just telling you something sounds off. This level of detail is what speech-language pathologists provide in accent reduction coaching, and it accelerates improvement significantly.
