Speech and voice controls, as each vendor documents them

The speech notes as one file

The notes are exported as one file. Each row records what a vendor documents about generated speech, with the page it was read from. As of 2026-09-12.

A file where the empty cells are most of the findingFour speech fields are kept for every model. Most models document the first and leave the rest unaddressed, so the file is dominated by rows recording that nothing is published.

Fig. 1 Exporting only the filled cells would describe a market where speech is well documented, which is not the market these notes found.

Speech is the least documented part of generative video, so this file is unusually full of rows recording that nothing is published. That imbalance is the most informative thing in it.

Each row names the field it fills, so a reader rebuilding the comparison cannot count a reference-audio claim as a native-audio one. Those two get merged constantly in product copy and the merge changes what a production has to plan for.

Nothing here comes from listening. Every row is a documented statement, which means the file describes what vendors commit to rather than what their models sound like.

Reuse under the licence below is permitted, including commercially, provided the source and date columns stay attached to the rows.

1What each column holds

One line of the export, explained. Recorded 2026-09-12.
ColumnWhat it holds
fact_idThe row's handle. Rewriting a note does not change it.
valueWhat the model's documentation states about speech.
applies_toThe control or language list the row is about.
source_urlThe documentation page it came from.
source_nameThe vendor's own name for that page.
value_sinceFrom when the documentation has said this.
verifiedThe last day that page was read.

Inclusion rule. Every recorded field is exported, including the many that record no published control. Order. File order follows recording order, grouping rows by model.
