Language tutor's 30 New Year micro-lessons: $0.90 as audio on Sume

A language tutor can produce 30 daily micro-lessons for January for $0.90 on Sume if each is a 600-character script voiced as audio: $0.03 per lesson, because 600 characters is $0.0285 and each job bills to the next cent. As 30 videos with one reused still, the total is $3.05 (read 2026-10-03).

A new year starts on Friday, January 1, 2027, and many learners start a language then. A 30-day series that ends on January 30 gives them something that fits a commute, and gives you a reason to message them every morning.

Writing for a voice

A micro-lesson is a short, rigid structure: the phrase in the target language, its meaning, one example, and one line for the learner to repeat. At 600 characters, spaces and punctuation included, you have room for about four lines. Write them as plain sentences. Voices read punctuation, so avoid parentheses and slashes.

Set language on every voice request and use a voice that speaks that language natively. If you send Spanish to an English voice you will get an accented reading,. For names, loanwords and anything the voice mispronounces, create a pronunciation dictionary once and send its id with every job. Listen to lessons 1 and 2 before generating the other 28; that is the cheap place to find a recurring error.

A native-speaker pass

Have a native speaker, ideally you or a colleague, listen to all 30 clips, with the script in hand. A synthetic voice can place stress wrongly on a word that a learner will then copy. Say on the first lesson that the voice is synthetic, and keep a recording of your own voice for the pronunciation drills that matter most.

Reuse is where the saving is. A lesson that needs correction is rerun for $0.03 as audio, and the video version costs $0.13 for the voice and render.

Budget and checks before you start

Plan the 30 days as four weeks of themes plus two review days: greetings, food, travel, work, and review. Writing the whole series before generating lets you reuse the same drill structure and spot gaps. Run the first three scripts, listen with the text in hand, and only then queue the rest.

If you teach in a language with regional variation, say which variety you want in the voice choice and the script spelling, and confirm with a native speaker that the voice matches. Learners notice inconsistent accents quickly.
