Features

• Learn — the full phonics curriculum: consonants, short & long vowels, digraphs, blends, vowel teams, diphthongs, r-controlled vowels, and soft c/g. Every phoneme has IPA, a plain-language articulation cue, example words, and one-tap voice-over.
• Practice — graded speaking sessions:
  • Intonation & Emotion — hear one sentence spoken happy, sad, angry, excited, as a question, and more. Pitch, pace, and stress are reshaped per emotion so learners hear how intonation carries meaning.
  • Minimal pairs (ship/sheep), tongue twisters, short everyday messages, and sentence drills.
• Rules — the exception/irregular spellings phonics can't predict: silent letters, the many sounds of ough, soft c/g, i-before-e, tricky sight words, the schwa, and doubling/drop-e.
• Accent + voice — switch between 🇬🇧 British (en-GB) and 🇺🇸 American (en-US) anywhere, and pick a female or male voice in Settings; choices are persisted.
• Feedback — send a note straight to the team via WhatsApp.
• About — app info, developer, learning reference, audio attribution, and version.

Voice-over

• Words — example words, minimal pairs, and rule examples play real human recordings sourced from Wiktionary / Wikimedia Commons (CC BY-SA), bundled for offline use, with an Apple TTS fallback for any word without a recording.
• Phoneme sounds — "Hear the sound" demonstrates a phoneme via AVSpeechSynthesizer fed a hidden pseudo-word cue tuned per sound (e.g. /iː/ → "ee", /eɪ/ → "ai") so the engine produces the isolated sound as closely as it can.
• Intonation & Emotion — emotion presets reshape the utterance's rate, pitchMultiplier, volume, delay, and punctuation so the synthesizer applies real rising/falling prosody.

Audio attribution is shown in the in-app About tab as required by the CC BY-SA license.
