Text-to-speech for sentences in two languages
I have translated a course from English to Spanish. However, there are a few terms and acronyms that need to said in English. They naturally appear throughout the sentences. I have used the text-to-speech functionality to create the audio.
Here's what I'm doing: I copy the beginning of the sentence (that's in Spanish) and paste it into the Text-to-Speech dialog box, choose the Spanish voice and click on Insert. Then I go back to copy the term/acronym (that's in English), paste it into the Text-to-Speech dialog box, choose an English voice and click on Insert. Lastly, I repeat my first step for the remaining Spanish words in the sentence.
My question is: Is this the most efficient way to generate the audio with the mix of Spanish and English in the same sentence?
