Why AskSia
What makes AskSia a strong tool to transcribe speech to text.
Most speech to text tools work in one mode: live mic, file upload, or browser capture. AskSia covers all four sources in one place, with the same speaker labels and translation across each.
Every speech source in one tool
Microphone for in-person speech, Browser Tab for Zoom and YouTube, file upload for recorded audio and video, podcast or video URL for online content. One transcriber covers them all without conversion.
Mic, browser tab, upload, URL
40+ languages, translated as you go
AskSia detects the source language automatically and can translate the transcript in real time across more than 40 languages. Read the original speech in one column and your preferred language in the other, sentence by sentence.
Auto-detect plus translate
Speaker labels for any conversation
Up to 10 distinct speakers identified automatically, color-coded and timestamped. Rename them after the fact, for example 'Host', 'Guest', or 'Student A', and the change applies to the entire transcript.

FAQ
Common questions about transcribing speech to text.
How do you transcribe speech to text?
To transcribe speech to text with AskSia, you record audio from your microphone, capture audio from any browser tab, upload an audio or video file, or paste a podcast or video URL. AskSia uses AI speech recognition to convert the audio into accurate written text in real time, usually within seconds for uploaded files and at sub-100ms latency for live recordings. The transcript includes timestamps and up to 10 speaker labels, and can be translated into more than 40 languages or exported as TXT, DOCX, or SRT subtitles.
What is speech to text transcription?
Speech to text transcription is the process of converting spoken words into written text using software. AI-powered tools like AskSia do this automatically with speech recognition models that identify words, speakers, and timing. The result is a timestamped transcript that can be searched, translated, edited, and exported to TXT, DOCX, SRT subtitles, or Google Docs.
Can AskSia transcribe live speech in real time?
Yes. AskSia transcribes live speech at sub-100ms latency from your microphone or any browser tab. Words appear on screen as they are spoken, useful for in-person lectures, online meetings, interviews, and dictation. Live sessions are unlimited on the free plan with no duration cap.
How accurate is AskSia at transcribing speech to text?
On clear audio, AskSia reaches 95 percent or higher accuracy. Accuracy depends on background noise, accents, and how many speakers overlap. The model uses context, which helps it correctly transcribe technical vocabulary, proper names, and academic terms that generic speech-to-text tools tend to misrecognize.
Can AskSia transcribe speech to text in multiple languages?
Yes. AskSia transcribes speech to text in more than 40 languages and detects the source language automatically. You can also run a translation at the same time, so the original transcript and a translated version appear side by side. Supported languages include English, Spanish, Mandarin, French, German, Portuguese, Japanese, Korean, Arabic, and Hindi.
Is the speech to text tool free?
Yes. AskSia is free to start with no credit card required. The free plan covers files up to 30 minutes and unlimited live speech to text sessions from your microphone or browser tab. AskSia Pro and AskSia Super remove the file duration cap and unlock features like Google Docs export, higher-accuracy tiers, and the full AI study companion.
What's the difference between speech to text and dictation?
Speech to text covers any spoken audio source, including lectures, meetings, interviews, podcasts, and recorded calls, where multiple speakers may be involved. Dictation is one specific use case of speech to text, where one person speaks intentionally to produce a draft document. AskSia handles both, with speaker identification for multi-person recordings and clean single-speaker transcripts for dictation.
