What you can practise on your own
Listening comparisons, short repetitions, recording and phrase rehearsal are practical solo tasks. Start with a sound you can identify in a model and a word you understand. The sound chart gives repeatable references, while the phrase library places useful lines in context.
Keep the model fixed during a comparison. Different speakers can pronounce a phrase differently; switching references every attempt makes it harder to decide whether your own production changed.
A solo practice routine
Listen to one short phrase twice. Record an initial attempt, select one physical or rhythmic change, and record again. Say what changed before replaying both versions. Then use the phrase in a response with one detail altered.
If you can imitate the model but cannot answer the prompt, the next task is speaking transfer. If you cannot hear the contrast at all, the next task is listening. Neither problem is solved simply by increasing your repetition count.
Where self-correction can fail
Familiarity with your own voice can make errors hard to notice. Automatic transcription can also accept a word without explaining its sound quality. Do not use either as a complete diagnosis.
A focused question helps when asking a teacher or proficient listener: “Do these two words sound different?” or “Which part of this request was hard to understand?” Bring a short recording and the intended text instead of asking for a judgment on your entire accent.
Choose support for the actual problem
For a sequence of independent exercises, use the beginner practice guide or Parle’s guided missions. For detailed personal correction, seek a qualified teacher. An app can organise repetition; it cannot guarantee that every pronunciation problem has been identified.
