Professor · Monetary Policy Seminar
Last week we separated temporary inflation from persistent pressure. 上周我们区分了暂时性通胀与持续性压力。 Today we compare supply shocks and demand-side policy responses. 今天我们比较供给冲击和需求侧政策响应。 Can we connect that to last week’s inflation model? 这能和上周的通胀模型联系起来吗？ Yes. Watch how expectations change the policy lag in this example. 可以。请注意这个例子中预期如何改变政策时滞。
Core product capabilities
LectBuddy starts with live transcription and translation, then turns the same lesson into a mind map, course quiz, AI Tutor answers, and an infographic.
Understand in real time
LectBuddy keeps live speech, source text, and translated meaning aligned, so students can follow the class without losing context.
Understand the structure
LectBuddy turns a linear transcript into timestamped branches, so students can scan the lesson and verify any concept in context.
Check what stuck
LectBuddy generates five lesson-based questions to show what students understand before an exam, assignment, or review session.
Ask the lesson
LectBuddy AI Tutor answers from the current lecture and cites timestamps, so every explanation can be checked against the source.
Remember visually
LectBuddy turns the topic, summary, keywords, and timeline into an exportable visual recap for faster review.
Start with a live class or upload a recording. LectBuddy keeps every study output connected to the original lesson.
Product film
From fast lecture speech to live bilingual understanding and searchable notes, this short film shows the product story from classroom pressure to a review-ready study asset.
Why LectBuddy
A second-language lecture can become a race against speech. LectBuddy keeps the live moment, its meaning, and the material students need later connected in one study workflow.
The problem
Miss one term, pause to translate it, and the next explanation is already gone. Accents, technical vocabulary, and note-taking pressure force students to choose between listening and recording what was said.
The LectBuddy advantage
LectBuddy turns classroom audio into live transcription and synchronized translation. Students can follow the original wording and translated meaning without leaving the lecture or switching between separate tools.
The study outcome
After class, the same LectBuddy session becomes chapters, bilingual notes, keywords, source-linked replay, and exportable material. Students return to the exact moment behind a concept instead of replaying an entire recording.
What LectBuddy does
LectBuddy packages transcription, translation, speaker context, keyword summaries, search, replay, and export into one web product. The goal is a complete study system for serious review.
LectBuddy captures live audio and turns speech into text while the class is still happening. Students can follow lectures through real-time transcription instead of waiting for post-class processing.
LectBuddy supports simultaneous translation for online classes, offline lectures, and meetings. Lecture translation helps students understand fast speech, different accents, and technical vocabulary.
LectBuddy keeps the original transcript and translated text together, turning class audio into bilingual notes that are easier to review before exams, assignments, and group discussions.
LectBuddy extracts keywords and main ideas from long recordings. Instead of rereading a complete transcript, students can start from the concepts that matter most.
LectBuddy lets students search any word or sentence in a session, then replay the exact moment at the right speed. This makes voice to text for students useful during real review.
LectBuddy can import recorded audio and export transcript results. Recordings, bilingual notes, and transcripts should remain under user control from capture to deletion.
Student wall
University of Manchester
Full-English class
“Long English lectures make it hard to stay focused. I import the key audio after class, generate an AI summary, and start revision from the important points.”
University of Sydney
Accented English
“My lecturer speaks English with a Spanish accent. The live transcript can still recognize the class clearly enough for me to keep up with the explanation.”
University of Toronto
Advisor meeting
“A friend recommended using the app when speaking with an advisor. Fast speech and specialist terms become much easier to follow in real time.”
Waseda University
Daily coursework
“I tried several translation tools. This is the one I kept using because the interface stays simple and does not interrupt the lecture.”
University of Melbourne
Everyday lectures
“A classmate recommended the study tool. Now I turn it on as class starts, so I can keep my attention on the lecture instead of chasing every sentence.”
Use cases
Lecture halls, Zoom classes, office hours, customer service calls, and interviews all create the same problem: important speech disappears quickly. LectBuddy turns that speech into reusable knowledge.
LectBuddy helps students follow teachers and classmates in real time. Accents, remote audio, and fast discussion are easier to handle when transcription and translation stay visible.
LectBuddy can capture the words students cannot type quickly enough. After class, the same recording becomes bilingual study material.
LectBuddy turns long recordings into searchable review paths. Students can find formulas, terms, examples, or professor hints without replaying the whole lecture.
LectBuddy is useful beyond class. Phone calls, interviews, customer service, and travel conversations become less stressful when important speech can be captured and translated.
Study workflow
LectBuddy works as a complete web workflow. Capture or upload audio, stream transcription, translate the important parts, then convert long sessions into structured study material.
01
Start a LectBuddy session before the lecture, meeting, or call. The browser workspace streams transcription while the student keeps attention on the speaker.
02
LectBuddy shows translated text beside the original speech. This keeps lecture translation useful in the moment, not only as a post-class cleanup step.
03
After the session, LectBuddy can clean punctuation, identify keywords, summarize sections, and align original transcript with bilingual notes.
04
Students review the transcript, jump to the matching audio, and export the result for notes, revision, collaboration, or personal archive.
Technical solution
LectBuddy uses OpenAI for realtime transcription, caption translation, spoken interpretation, and study intelligence.
OpenAI
OpenAI transcription, translation, spoken interpretation, and study-note generation.
OpenAI provides realtime source captions and translates committed text. LectBuddy manages connection recovery so live captions can continue when a session reconnects.
OpenAI turns uploaded lectures, seminars, and calls into timestamped source text for review and speaker-aware processing.
Use advanced OpenAI language models to clean transcripts, correct terminology, extract keywords, summarize lectures, and generate bilingual notes.
Privacy first
LectBuddy handles sensitive class, meeting, and call content. The product should keep data control clear, preserve deletion paths, and avoid using private learning data for model training by default.
LectBuddy users should be able to delete recordings, transcripts, translations, summaries, and exported files when they no longer need them.
Private lecture and call content should not be used for model training by default. Sensitive data deserves explicit boundaries and clear retention rules.
Audio files, transcript text, bilingual notes, and exports should be stored as separate resources with scoped access and short-lived download links.
Languages
LectBuddy supports the multilingual reality of study abroad. English and Chinese are the core use case, while broader language coverage helps students move through meetings, travel, and daily life.
The core LectBuddy use case is study abroad: English lectures, Chinese subtitles, bilingual notes, and mixed-language classroom discussion.
Spanish, French, German, Italian, Portuguese, Dutch, Polish, Swedish, Ukrainian, and more help students handle regional coursework and travel.
Japanese, Korean, Thai, Vietnamese, Hindi, Bengali, Malay, Tamil, Telugu, Urdu, Cantonese, and others support broader international study.
LectBuddy is positioned around broad language coverage, giving the product a global story beyond one lecture translation pair.
