Who said what? Finally clear.

When multiple voices fill a recording, knowing who said what separates crystal-clear action items from a fog of ambiguity. AdjiCera identifies each speaker, lets you name them, and tags every action item to an owner.

The challenge

Recordings are messy. When you play back a meeting or interview, you hear multiple voices layered together. Computers can transcribe every word, but without knowing who said each word, you're left with a question every few sentences:

Who owns this action?

"We need to finalize the budget by Friday." But who? Speaker 1? Speaker 2? You still don't know.

Which interviewer said it?

In an interview, mixing up who asked what undermines the assessment. You need to know: was this the hiring manager or the technical lead?

Follow-up: "Who did we assign this?"

You send a follow-up email days later. The transcript says "I'll handle the research," but you forgot which participant said it.

How AdjiCera solves it

AdjiCera identifies speakers automatically, then gives you full control over who is who.

🎙️

Automatic speaker detection

AdjiCera analyzes the audio and identifies distinct voices. Each speech segment is labeled as "Speaker 1," "Speaker 2," etc.

👤

Name your speakers

You rename speakers to their actual names: Sarah, Marcus, your own name. No signup. No external database. Names stay on your device.

✏️

Correct mistakes

If the audio was noisy or voices overlapped, you can reassign any segment to the correct speaker. A few clicks, and your transcript is accurate.

Tag action items to owners

When AdjiCera extracts action items, each one is tagged to the speaker who said it. "Marcus Davis → Lead budget review by Friday."

What changes

For students (group study)

  • Study with two friends. Know who explained which concept.
  • Review: "Alex asked the follow-up question about photosynthesis."
  • Quiz yourself on who said what — reinforces learning.

For professionals (meetings & interviews)

  • Interview: Know which interviewer asked each question — critical for evaluation.
  • Action items auto-draft with owner names: "Sarah → finalize budget."
  • Follow-up email is ready. No more "who did we assign this to?"

Built on your device

Everything stays on your device by default. Speaker identification, naming, corrections — none of it touches the cloud. Your recording, your transcript, your participant list stay private, with the one exception being if you choose to use optional Prime AI features, which process transcript text you send and never store it.

No signup required. No API keys. No meeting bot joining your video call. You own your data.

What is speaker diarization?

Speaker diarization is the process of analyzing an audio recording to determine who said what and when. It partitions the audio into segments and assigns each segment to a speaker. AdjiCera performs this analysis on your device, without sending audio to the cloud.

Can I fix mistakes?

Yes, completely. You can rename any speaker, reassign transcribed segments to the correct speaker, merge speakers (if the algorithm split one person into two identities), or split speakers (if it merged two people). Full manual control.

How many speakers can it handle?

AdjiCera is optimized for 2–4 speakers in most meeting and interview scenarios. For more participants, you can manually merge or split speakers to clarify the transcript. Highly overlapped or crosstalk-heavy audio may need manual corrections, but manual merge/split controls give you full flexibility.
