Audio Cards

Record voice notes on mobile and Neurako transcribes them into flashcard drafts using AI.

On mobile, you can record a voice note and Neurako will transcribe your speech and generate flashcard drafts from it. It's particularly useful for capturing spoken vocabulary, dictating study notes, or summarizing lecture content hands-free.

Key Takeaways

Audio capture is mobile-only — web does not support microphone recording to cards - The AI transcribes your recording and extracts card candidates from the spoken content - Structured speaking (Q&A format, clear pauses between concepts) produces cleaner drafts - Transcription is never perfect — always review generated cards before saving

How audio cards work

Open the Create tab in the Neurako mobile app and tap the microphone icon.
Tap the record button and speak your study material clearly into the microphone.
Tap stop when you're done. Neurako uploads the audio and begins transcription.
The AI generates card drafts from the transcribed text. A preview screen shows every draft.
Edit, delete, or add cards as needed, then save to your deck.

Transcription and card generation happen on Neurako's servers. Processing time depends on the length of the recording — a one-minute note typically takes a few seconds.

What audio cards are good for

Vocabulary practice — Speak a term and its definition. The Q&A structure maps directly onto card fronts and backs. For language learning, dictating "What is the Spanish word for 'window'? — Ventana" gives the AI a clean card candidate.

Lecture summaries — After a class or lecture, record a quick spoken summary of the key points while they're fresh. The AI can extract the main concepts into card drafts that you refine later.

Spoken study material — If you have notes you understand but haven't converted to cards yet, reading them aloud into the recorder is faster than typing them into the create screen.

Language pronunciation — Record yourself pronouncing vocabulary words and use the resulting cards to quiz yourself on spelling or meaning alongside the audio context.

Mobile

Audio recording is available in the Create tab using the microphone icon. This feature requires microphone permission — Neurako will prompt you for access the first time you try to record.

Audio quality affects results

Transcription accuracy is directly tied to recording quality. A few factors that matter:

Environment: Quiet environments produce better transcriptions. Background noise — traffic, conversations, music — introduces errors in the transcript that carry over into the card drafts.

Pronunciation and pace: Speaking clearly and at a normal pace gives the transcription model more to work with. Very fast speech, heavy accents, or mumbled words increase error rates.

Pauses between concepts: A natural pause between distinct ideas helps the AI identify where one concept ends and another begins. Running everything together produces denser, harder-to-parse drafts.

Structure your recording for better cards

The AI generates cards from whatever you say — but the quality of those cards depends heavily on how you organize your speech. Rambling or stream-of-consciousness recordings produce noisy drafts with awkward splits.

A few specific patterns that work well:

Definition cards: "What does [term] mean? — [definition]."
Concept explanation: "What is [concept]? — [1-2 sentence explanation]."
List cards: "Name three causes of [event] — [cause one], [cause two], [cause three]."

Avoid long, continuous explanations without pauses. The AI will attempt to segment them, but longer unbroken recordings tend to produce larger cards that are harder to review.

Reviewing transcription output

Transcription is rarely perfect, especially for technical vocabulary, proper nouns, or domain-specific terminology. After the AI generates card drafts:

Check the transcript: If the source text looks wrong, the card drafts built from it will be wrong too. Fix the front-and-back text directly in the preview.
Merge or split cards: The AI may combine two related ideas into one card or split a single idea across two. Edit as needed.
Delete noise: Filler words, re-stated sentences, or off-topic asides sometimes make it into drafts. Delete anything that isn't useful study material.

The review step is always required — audio cards are drafts, not finished output.

Language support

Audio transcription supports the same languages as Neurako's app interface. Speak in the language your study material is in, and the AI will transcribe and generate cards in that language.
