How do I transcribe a WAV file to text?
Drag the WAV file into AskSia, or click upload and select the file from your computer or phone. AskSia processes the audio with AI speech recognition and returns a timestamped transcript with up to 10 speakers labeled automatically, usually in seconds. The transcript can be translated into more than 40 languages and exported as TXT, DOCX, or SRT subtitles. The free plan covers WAV files up to 30 minutes.
Do I need to convert WAV to MP3 first?
No. AskSia transcribes WAV files directly, including high-resolution 44.1 kHz, 48 kHz, and 96 kHz PCM WAV recordings at 16-bit or 24-bit. There is no need to compress to MP3 or M4A first. WAV often produces slightly higher transcription accuracy than compressed formats because no audio detail is lost.
How accurate is AskSia at transcribing WAV files?
On clear WAV audio, AskSia reaches 95 percent or higher accuracy, often the highest accuracy possible because WAV preserves full audio detail. 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 transcribers tend to misrecognize.
How long can the WAV file be?
The free plan supports WAV files up to 30 minutes per upload. AskSia Pro and AskSia Super remove the duration cap entirely, useful for full lectures, multi-hour interviews, recorded conferences, and long studio sessions where WAV is the standard delivery format.
What WAV sample rates and bit depths does AskSia support?
AskSia supports the most common WAV configurations, including 44.1 kHz and 48 kHz at 16-bit and 24-bit, plus 96 kHz studio recordings. Mono and stereo files are both handled. There is no need to downsample or convert to a specific spec before uploading.
Can AskSia transcribe WAV files in other languages?
Yes. AskSia transcribes WAV files in more than 40 languages and detects the source language automatically. You can also translate the transcript at the same time, so the original audio and a translated version appear side by side. Supported languages include English, Spanish, Mandarin, French, German, Portuguese, Japanese, Korean, Arabic, and Hindi.
What other audio formats does AskSia support besides WAV?
AskSia supports WAV, MP3, M4A, OGG, FLAC, AAC, WMA, AIFF, AMR, and most other common audio formats. There is no need to convert your file before uploading. AskSia also accepts video files like MP4 and MOV and transcribes the audio track directly.
