For a lot of people, studying a piece of content in Aelano looks like this: open it → listen while reading the bilingual subtitles → reach the end → close it. You did listen once, but how much did you actually retain? Very little, in practice — because your brain was never forced to engage. Aelano's Practice (LS100) is a focused listening routine applied to each piece of content. It splits long content into short segments, and each segment goes through four steps: look at the vocabulary first, then blind listening, then focused listening, then shadowing. By the time a segment is done, that material has passed through your head four times — that is what counts as having learned it, rather than having heard it.
"LS100" stands for understanding 100%.
Open any content that has already been transcribed and enter the player. There are two tabs at the top of the player:
When you switch to Practice, if the content has not been split into segments yet, Aelano walks you through creating segments — you choose how long each segment should be, then start the routine.
If nothing has been split yet when you open Practice, you see a prompt to turn on segment study mode.
Aelano asks you how long each segment should be:
Once it is split, the whole piece becomes a series of short segments you can work through in order.
If you are not happy with the result, you can split it again — the content is re-cut, but your sentence recordings and shadowing scores are kept (the scoring history is not lost); the practice progress for each segment (blind listening / focused listening / shadowing completion) is reset.
For each segment, Practice takes you through the following order:
When you enter a segment, you first look at the key vocabulary that Aelano's AI automatically extracted from it.
This step is a warm-up — it activates the semantic network in your head first.
Switch to blind listening mode: no subtitles on screen, just sound.
What matters most in this step is not what percentage you understood, but that you actually listened. Even if you only catch 30%, you improve faster than if you lean on subtitles the whole time.
Switch to focused listening mode: subtitles and translation are both on.
Switch to shadowing mode: you read along with each sentence, and AI scores you word by word.
After you shadow a sentence, each word is highlighted by color:
You can use the colors to work out which sounds you did not land, listen to the original again, and read it again.
Each sentence records how many times you listened and how many times you read it — giving you a concrete sense that you are really practicing.
If you feel the AI scoring is too strict (marking you wrong when you clearly read it correctly), you can loosen it in the shadowing scoring settings.
Once all four steps are done, the segment is marked as complete.
You can then:
How does Practice relate to the normal Transcript tab?
They are two ways of studying the same content. Transcript is the default listen-while-reading-subtitles mode, good for getting through a lot of material, passive listening, and light study. Practice is the close-study mode, for content you really want to master. You can switch back and forth at any time.
Does Practice require a membership?
You do not need a membership to use the full routine — the three steps of vocabulary preview / blind listening / focused listening are free forever and consume no points. Only step 4, shadowing, consumes points — because AI has to score your pronunciation word by word, which is a pay-per-use AI feature. Free users can use it too; each shadowing attempt simply deducts points. If you practice shadowing heavily, a membership is worth considering for the more generous monthly allowance.
There is no split button — why did Practice start straight away?
If this content was split into segments before, Practice starts right away using the existing segments. If you want to re-cut it, choose Split again.
Is the shadowing score accurate?
Scoring is relatively accurate for major languages (English, Japanese, Korean, Chinese, German, French, Spanish, and so on). Accuracy may be lower for less common languages. If the scoring feels off, you can adjust the strictness in the scoring settings.
Do I have to follow the 1 → 2 → 3 → 4 order in every segment?
It is not enforced. You can start from any step, and you can skip a step — but pairing at least blind listening and focused listening works best.
Why do some segments have no vocabulary review step?
If the AI did not identify any words worth reviewing in that segment (the content is too easy, or every word is one you have already mastered), the step may be skipped.
What about microphone permission for shadowing?
Shadowing requires Aelano to access the microphone — iOS and Android prompt for permission the first time you enter shadowing. If you declined, you can turn it back on in your system settings.
