๐น Starter Activity: Make a 5-Word Sentence
Tool: Word Synth
- Type a short sentence (e.g. โMy cat plays the pianoโ).
- Listen to how the machine โspeaksโ.
- It helps machines read, write, speak, and make sense of our words.
- Itโs used in tools like Google Translate, autocorrect, chatbots, and voice assistants.
๐ง Word Synth uses NLP and speech synthesis to turn your sentence into sound โ trained on real speech to sound realistic.
