Text to speech for teachers: classroom audio without a recording booth
Teachers record more audio than anyone expects: a listening task for Friday, a story for the reading corner, instructions for a student who missed the lesson, a message to parents who read another language better. Recording every version yourself takes evenings, and every typo means a new take.
SuperClonica gives you natural voices in 31 languages, free to try online, and a free engine that runs offline on a school computer, so student names and class texts never leave it. This guide shows the classroom uses that work best and how to make the audio quickly.
Where text to speech helps in class
A synthetic voice does not replace your own voice in class; it saves your evenings for the recordings that need you.
- Listening tasks: the same voice and speed for every version of a test.
- Read-along stories for young readers, slower than normal speech.
- Instructions for students who missed a lesson or need to hear them again.
- Messages to parents in the language they read best.
Try a voice free online
On the page of any voice, type a sentence from your lesson, 30 to 100 characters, choose the language and press Voice it. Pick a calm, clear voice that students will hear all year.
Make audio for a lesson
Keep one voice per class or subject: students get used to it and focus on the content.
- Install the free engine: python -m pip install superclonica-cpu.
- Voice a story at a slower pace: superclonica --text-file story.txt --voice F2 --lang en --speed 0.9 --normalize --output story.mp3.
- Write numbers and dates in words for young students: digits are read as plain numbers.
- For a listening test, voice each question as its own file and leave the answer time in your player or slides.
Worksheets, parents and absent students
Put the MP3 files in your class drive and link them from a worksheet with a QR code, so students can listen at home on a phone. For parents, write the message once, translate it and voice each language with a voice that sounds natural in it; most catalog voices were recorded in Russian, so for other languages listen first or use the ten stock voices. The engine has no character limit and every file comes out at the same loudness, −18 LUFS.
Privacy and fair use
The engine runs on your computer, so student names, grades and notes are not sent anywhere. The free online test sends only the sentence you type. Voicing a published textbook for your own class is one thing, sharing the audio publicly is another, so follow your school’s rules. For audio you share, use the ten stock voices, M1 to M5 and F1 to F5, free under the OpenRAIL-M license, or your own voice trained in the SuperClonica studio.
