DivX to VOX Converter
Extract DivX video audio as Dialogic VOX ADPCM online
Video to Phone Audio
Extract voice content from DivX and encode as VOX — the standard format for Dialogic IVR systems and telephony voice prompts.
Highly Compressed
VOX ADPCM keeps audio files tiny at 4 bits per sample. Ideal for telephony systems where storage per prompt must stay minimal.
Server-Based Encoding
All audio extraction and VOX encoding runs on our servers. Upload your DivX, download VOX — zero local tools required.
How to convert DIVX to VOX
Select files from Computer, Google Drive, Dropbox, URL or by dragging it on the page.
Choose vox or any other format you need as a result (more than 200 formats supported)
Let the file convert and you can download your vox file right afterwards

Frequently Asked Questions
VOX is the go-to format for Dialogic telephony hardware and IVR systems. Converting DivX audio to VOX builds phone system prompts from video.
VOX packs audio into 4-bit ADPCM, achieving roughly 4:1 compression versus raw PCM. This makes telephony storage very space-efficient.
No — VOX is a headerless raw ADPCM format. Playback systems need to know the sample rate (usually 8kHz) when loading VOX files.
VOX is optimized for speech in telephony settings. Music quality is noticeably degraded — use MP3 or FLAC for music preservation.
Yes — upload multiple DivX videos and convert them to VOX simultaneously. Efficient for creating libraries of telephony voice prompts.
