Variants by level

FAQ

What length of speech should I ask Mistral for a 10-minute talk?

A speaker averages 130 words per minute in French. For a 10-minute speech, request about 1,300 words. Specify this constraint in your prompt so Mistral calibrates the length correctly. You can also directly indicate the desired duration and let the model adapt the text volume, but always check the result by reading it aloud with a timer.

How can I adapt the tone of the speech generated by Mistral to my personal style?

Provide Mistral with an excerpt from a speech or text you have already written by adding to the prompt: "Here is an example of my writing style: [EXCERPT]. Adapt the speech to match this tone and voice." You can also specify concrete preferences: use of formal or informal address, level of formality, use of humor, or expressions you frequently use.

Can Mistral write a bilingual speech or with passages in another language?

Yes, Mistral handles multilingualism very well. Specify in your prompt the passages that should be in another language and the context of this alternation. For example: "Include a quote in English followed by its French translation" or "Start with a greeting in Arabic before continuing in French." Mistral will naturally adapt transitions between languages while maintaining speech coherence.
