Record the Spanish take first, or the Spanish version never gets recorded
Every clip a bilingual firm makes is two clips, and the plan has to be built around that from the start.
The pattern that fails is familiar. The English version gets recorded on the day, the Spanish one gets scheduled for later, and later never arrives because the attorney is at the Eleventh Judicial Circuit all week.
So invert the order. Record the Spanish take first, on the same subject, before anyone is tired. If only one version survives the day in this county, it should be that one.
Write the Spanish version rather than translating the English one. Same subject, different script, because the questions people actually ask are phrased differently and the useful examples are not the same.
Budget the session honestly. A recording day yields around half the topics it would for a single language practice, which is an argument for covering fewer subjects properly rather than a long list thinly.
