Lithuanian lectures from an AI agent:
listen, watch or read

Short answer. Ask Claude or ChatGPT with the Talkfirst connector for a short lecture, and the agent writes a script and builds it on the server with lesson_create: explanations in English, Lithuanian phrases in a Lithuanian voice, slides and exercises. The lesson opens in the chat or waits on the Lessons tab, where you can listen, watch or read it later.

When you ask an AI chat why it is sergu in one sentence and sirgti in the dictionary, you get a good answer and a long one. You read it once and it is gone. A lecture is the same explanation turned into something you can listen to on the way to work, with the Lithuanian said in a Lithuanian voice. This guide shows how an agent builds one with Talkfirst and what you get.

How the agent builds a lecture

You ask: “Make a short lecture about …”. The agent first reads docs("lessons"), then writes a script made of scenes. A scene can be an explanation in your explanation language, a Lithuanian phrase said by its own Lithuanian voice, a slide, a table or an exercise. Then it calls lesson_create.

The lesson is assembled on the server in the background, not in the chat. A lesson of about eight scenes with new voicing takes roughly 15 seconds; anything already voiced comes from the cache. If something in the script is wrong, the agent sees the error straight away and fixes it.

Afterwards the lesson opens as a window in the chat with lesson_open, and it also stays on the Lessons tab of the app. That is the point: you can ask on your laptop “prepare three lectures for the week” and listen to them later from your phone.

A lecture on the verb būti in the player: a table of present and past forms, subtitles, −10 / +10 seconds and speed. A frame from our test setup, not a screenshot of a live chat.

Three ways to take one lesson

• Listen — sound only. You can turn the screen off: on a walk, on the bus, in the car between deliveries.
• Watch — slides or subtitles along with the sound.
• Read — the text without sound, with a ▶ next to each phrase so you can hear just that one.

There is a speed control and ±10 seconds. A lecture is not interactive: it does not wait for your answer. For speaking there are the pronunciation window, quizzes and conversations.

What goes into a lecture

The agent sizes the lesson to your level. At A1–A2 a lecture is 10–20 scenes, with explanations taking up to half; new phrases are said more slowly and repeated. At B1–B2 more of the lesson is in Lithuanian. Grammar always comes with slides: a table, the rule and an exercise.

The voice of the explanations is English or Russian, following your interface language; with an English interface you hear English. Lithuanian phrases are always said by a Lithuanian voice. All voices are speech synthesis.

The agent keeps no more than five unfinished lectures on one topic, and it doesn't hammer the same problem word more than once a week.

Prompts

Grammar with a table

Make a 5-minute lecture on the verb būti: present and past, A2. A table slide, three example sentences and a short exercise at the end.

A real situation

Make a lecture for a visit to the family doctor: Norėčiau užsiregistruoti pas šeimos gydytoją, Ką jums skauda?, Man skauda galvą. Explain each phrase briefly, say the Lithuanian slowly and repeat it.

Your weak spots

Make a lecture on my weak spots from the last two weeks.

With topic: weak_spots the agent collects your mistakes from quizzes, slow words from word_stats and corrections from your conversations, and builds the lesson from them.

For the week ahead

Prepare three short lectures for the week, for listening on the bus: public transport, renting a flat, and phrases for work with customers.

The lectures appear on the Lessons tab; nothing needs to be open while they are assembled.

Before the oral exam

A lecture on answering “Kiek laiko gyvenate Lietuvoje?” and “Ar turite vaikų?” in the oral A2 exam: two or three ways to answer each, with a short pause for me to repeat.

Questions for the oral part are collected in A2 speaking questions, and the mock exam itself is on the A2 exam page.

Ready lectures for Lithuanian

You don't have to start from an empty tab. Lithuanian already has ready lectures on the topics of the course decks for A1–A2, on the Lessons tab. Lectures your agent builds sit next to them, so the tab becomes your own small course: the ready base plus lessons on exactly what you got wrong this week.

Limits

New voicing counts towards the weekly limit: the free plan has 210 new voicings a week. If they run out, a new lecture will not build until Monday, or with Pro. Phrases that were already voiced come from the cache. There is no file to download: “offline” here means the lesson is built without you and you listen to it later, in the app.
