Practice flow

From import to review, built around the sentence you are practicing.

Vocer keeps the workflow focused: find a phrase, repeat it, save it, and come back when it is time to review.

01Practice

Practice one sentence at a time

Start from the current sentence and stay in the practice context. Playback, pause, rewind, and continue are all close to the material you are training on.

Resume recent practice without hunting through files.
Useful for dictation, shadowing, close listening, and speaking practice.

02Loop

Loop the exact phrase

Set A and B points around the hard phrase, then repeat just that moment. Adjust speed and repeat count until the details become clear.

Repeat short phrases, connected speech, pauses, and intonation.
Save segments so you can return directly to the important part.

03Library

Import audio your way

Bring in audio from Files, AirDrop, or file sharing, then keep it in a clean local materials library. Vocer stays centered on practice instead of becoming a generic file browser.

Local import and local material management.
Keep audio, segments, and learning records connected.

04Review

Review what matters

Save the clips that deserve another pass. The review page brings you back to favorite and saved segments instead of making you scan the full recording again.

Review favorite and saved clips in one place.
Turn repetition into a growing practice record.

05Settings

Personalize every repeat

Default repeat count, playback speed, import behavior, local data cleanup, and legal links are kept clear in Settings.

Control repeat count, speed, and import behavior.
Clear learning records and view the Privacy Policy and Terms of Service.

FAQ

Before you start.

What materials work well?

Podcasts, lecture audio, listening materials, speaking practice files, and local recordings you already have the right to use.

Does Vocer manage study plans?

No. Vocer is a local listening and speaking practice tool focused on import, repeat loops, saved clips, and review.

Why focus on A/B repeat?

Language practice often breaks down in a few seconds of connected speech, weak forms, intonation, or pauses. Short-loop repetition is more focused than replaying an entire file.

Where is the privacy policy?

You can read the Privacy Policy and Terms of Service for data handling and use rules.
