French speech to text: published results

By the Potok teamUpdated ~2 min read

French speech to text in Potok is a recommended language. Published large-v3 tests give word error rates between 5.3 and 6.31, from several sources, not our own measurement. French spelling hides many sounds, so errors tend to be about spelling rather than hearing.

Key facts

  • Several published sources agree within about one point, which is a steadier picture than a single paper.
  • Many French words sound alike but are spelled differently, and context decides which one the text uses.
  • Agreement endings such as plural s or e often cannot be heard, so they depend on grammar.
  • Canadian and European speakers differ in pronunciation, and the figures do not separate them.
  • Liaison links the end of one word to the start of the next and can blur word boundaries in fast speech.

What a transcript looks like

Sample sentence in French
[00:00] Speaker 1: Commençons la réunion. D'abord, nous passerons en revue les résultats de la semaine dernière, puis nous planifierons les prochaines étapes.

Meaning in English: Let's start the meeting. First, we'll review last week's results, then plan the next steps.

How to do it

  1. Choose your speaker. Note whether the voice is from France, Canada or elsewhere.

Frequently asked questions

What is the published range?

From 5.3 to 6.31 word error rate for large-v3, taken from several published tests.

Why are there several numbers?

Different tests use different audio and text rules, so they do not match exactly.

Does it support Quebec French?

The tests do not separate it from other speech, so try a short sample from the speaker.

Is the transcript in French?

Yes, it stays in French because the bot does not translate.

How big can the file be?

Files up to 2 GB are accepted, with the Upload button for the largest recordings.
