Quick Answer
What is an AI transcriber?
An AI transcriber is software that uses artificial intelligence to turn spoken audio into written text in real time. AskSia is an AI transcriber made specifically for students. It works on live lectures from your microphone, audio playing in any browser tab (so it covers Zoom, Google Meet, and YouTube), and files you upload from your device. AskSia supports more than 40 languages, identifies up to 10 different speakers automatically, and runs at sub-100ms latency. Every transcript also comes with Sia, a built-in AI assistant that can summarize the audio, generate flashcards, or answer questions while the recording is still playing. The free plan covers files up to 30 minutes and unlimited live sessions, with no credit card required.

Why AskSia
What makes AskSia different from other AI transcribers.
Most transcription tools were built for business meetings. AskSia was built for the way students actually learn: across multiple languages, full of academic vocabulary, and at the speed of a real professor.
40+ languages, translated live
AskSia transcribes and translates at the same time. Listen to a Mandarin lecture and read English notes, or follow an English seminar in Spanish. The translation runs alongside the transcript, sentence by sentence.
Simultaneous translation
Works with any audio source
Record live with your microphone, capture audio from any browser tab (Zoom, Google Meet, YouTube), upload existing files, or paste a podcast or video URL. One AI transcriber covers every way audio reaches a student.

An AI study assistant on the side
While the transcript is being built, you can ask Sia anything about what has been said so far. Get a summary at the break, generate flashcards on the spot, or ask why the professor used a specific term.

Use Cases
What students transcribe with AskSia.
In-person lecture halls
Set your phone on the desk and start recording. AskSia captures every word, even from the back row of a 300-seat auditorium, and labels each speaker as the discussion moves.
Mobile and Web
Zoom and online classes
Browser Tab capture works with any audio playing on your computer: Zoom, Google Meet, Webex, Teams, or recorded lecture videos. There is nothing to install and no calendar permissions to grant.
Browser Tab capture
Podcasts and seminars
Paste a YouTube or podcast URL and AskSia turns it into searchable, translatable text. Useful for research seminars, guest lectures, and any audio you want to revisit later.
Any audio source
Exam review sessions
Record your study group, then ask Sia to pull out the key topics or generate practice questions from what was actually discussed. The hard part of reviewing turns into reading.
AI-generated quizzes
Bilingual and code-switching courses
Plenty of professors switch languages mid-sentence. AskSia detects the change automatically, transcribes both languages, and translates everything into one clean record.
Multi-language detection
Recorded lectures and files
Upload any MP3, MP4, WAV, M4A, OGG, WEBM, or MOV file and AskSia returns a full transcript with translation in seconds. There is no file conversion step.

FAQ
Common questions about AskSia AI Transcriber.
What is an AI transcriber?
An AI transcriber is software that uses artificial intelligence to turn spoken audio into written text. AskSia is an AI transcriber made for students. It works on live lectures, Zoom recordings, YouTube videos, and uploaded audio files, supports more than 40 languages, identifies up to 10 different speakers automatically, and includes a built-in AI study assistant that can summarize the audio or generate flashcards from it.
What audio and video formats does AskSia support?
AskSia accepts MP3, MP4, WAV, M4A, OGG, WEBM, and MOV files. You can also transcribe from a YouTube URL, a podcast link, or by recording live through your microphone or browser tab. There is no need to convert files first.
How many languages can AskSia transcribe and translate?
AskSia transcribes in more than 40 languages and can translate to any supported target language at the same time. The list includes English, Simplified and Traditional Chinese, Korean, Japanese, Spanish, German, French, Portuguese, Arabic, Hindi, and most major European and Asian languages. The source language is detected automatically.
How accurate is AskSia's transcription?
On clear audio in typical lecture conditions, AskSia reaches 95 percent or higher accuracy. Accuracy depends on audio quality, accents, and background noise. The model also uses context, so academic terms like 'antiderivative' or 'photosynthesis' come through correctly instead of being misheard as common words.
Can AskSia identify different speakers automatically?
Yes. AskSia automatically labels up to 10 distinct speakers in a single session, color-coding their turns and timestamping each one. After the recording you can rename speakers, for example 'Prof. Chen' or 'Student A', and the change applies to the whole transcript.
Is my audio data private and secure on AskSia?
Audio files and transcripts are encrypted both in transit and at rest. AskSia does not sell or share your data with third parties, and your content is not used to train AI models. Files are processed and then deleted unless you choose to save them to your library.
How much does AskSia cost?
AskSia is free to start, with no credit card required. The free plan covers files up to 30 minutes each and unlimited live recording sessions. AskSia Pro and AskSia Super unlock unlimited file duration, higher-accuracy tiers, Google Docs export, and the full AI study companion.
