QuickTime to Speech Data

Extract dialogue from MOV video and package it as NIST SPHERE — the benchmark format for speech corpus distribution and ASR training.

Any Platform

Convert MOV to NIST from any device with a browser. No Apple software or SPHERE toolkit needed — just upload and download.

Data Security

MOV uploads are deleted after processing. NIST output is removed within 24 hours — your speech research materials stay confidential.

Let the file convert and you can download your nist file right afterwards

About formats

MOV is a multimedia container format developed by Apple Inc. and introduced in December 1991 with the launch of the QuickTime multimedia framework. As the native format of QuickTime, MOV pioneered many concepts that later influenced the ISO base media file format (MPEG-4 Part 12) and its derivatives, including MP4. The container uses a hierarchical atom (or box) structure where each atom holds specific types of data — from video and audio tracks to metadata, text, and timecode information. MOV supports an extremely broad range of codecs including H.264, HEVC, ProRes, Apple Intermediate Codec, AAC, and PCM, among many others. This codec flexibility, combined with features like multiple track support, reference movies, and edit lists, has made MOV a staple of professional video production. The ProRes codec from Apple, commonly delivered in MOV containers, is an industry standard for post-production and broadcast finishing. The format handles both compressed delivery-quality content and high-bit-rate production-quality footage with equal capability. Precise timecode and metadata handling make MOV particularly valued in workflows requiring frame-accurate editing and reliable exchange between production tools. MOV is natively supported across all Apple platforms and widely recognized by professional editing software on all operating systems, maintaining its relevance across decades of evolving video technology.

NIST SPHERE (SPeech HEader REsources) is a specialized audio file format created by the National Institute of Standards and Technology for speech research, particularly projects funded by DARPA. The format wraps raw audio samples with a structured ASCII header encoding metadata such as sample rate, channel count, encoding type, speaker demographics, and transcription annotations — making it ideal for distributing speech corpora. NIST files typically store uncompressed PCM or mu-law audio at telephone-quality sample rates (8 kHz or 16 kHz), though the container is flexible enough to hold various encodings. A key advantage is the rich self-documenting header that lets researchers embed detailed corpus metadata directly in the file, eliminating sidecar files. SPHERE has also become the de facto standard for major speech databases like TIMIT, Switchboard, and the Fisher corpus, ensuring broad recognition across academic and government labs. The open specification and availability of command-line tools (sphere, h_strip, w_decode) make it straightforward to convert, inspect, and process these files programmatically in speech processing pipelines.

Frequently Asked Questions

Why convert MOV to NIST?

NIST SPHERE is the benchmark for speech research audio. Extracting MOV dialogue into NIST creates properly formatted data for ASR training.

What frameworks support NIST?

Kaldi, HTK, the NIST SPHERE toolkit, and most academic ASR platforms work directly with NIST-formatted speech audio files.

Is MOV a good speech source?

MOV from Apple devices often has clean audio capture. This makes QuickTime recordings good source material for speech research datasets.

Does NIST compress audio?

No — NIST stores PCM without lossy compression. MOV audio reaches the SPHERE format at full quality for accurate speech analysis.

How does NIST compare to SPH?

NIST and SPH are the same format — SPHERE by the National Institute of Standards and Technology. The extensions are interchangeable.
