Words, chapters, and minutes: understanding your audio balance
Why a word count does not equal a fixed number of minutes and how to check how much your recording covers.
Words, chapters, and minutes are different measures. A chapter may be short or very long. A given number of words can be narrated at different paces depending on language, voice, and pauses. That is why it is not accurate to advertise a fixed number of minutes for any given balance. In Vox, it is worth checking what generation your account covers and then checking the duration of the resulting file.
What a word-based allowance measures
A word-based allowance limits how much text goes into a generation. On its own, it does not indicate how many complete chapters you will hear. Vox's free credits cover up to 200 words per selected chapter; if that chapter exceeds this length, the file may contain only an excerpt.
Additional words are displayed separately. Before generating audio, distinguish your available balance from the history of files you can already play.
Why duration varies
The voice may make different pauses between sentences and names. The language and the form of the text also have an influence. A list and a dialogue are not necessarily narrated at the same pace. Do not extrapolate the duration of a single example to an entire package.
If you need to know the actual number of minutes, check the player after generating audio. When planning a session, also set aside time to read context and take notes, not just to listen.
Check the unit of text
Locate the beginning and end of the audio in Sefaria or your edition. If the file ends before the last verse, mark it as partial. This check prevents a chapter label from being confused with a complete reading.
To compare languages, keep equivalent references and do not rely solely on duration. Two files with different running times may cover different portions or narrate the same text at a different pace. A note recording the balance used, the reference, and the actual endpoint helps you organize subsequent sessions without turning time estimates into promises the system does not guarantee.
