+ This is a demonstration of Sesame AI's CSM-1B Conversational Speech Model.
262

263
+ * The model can generate natural sounding speech from text input
264
+ * You can choose different speaker identities by changing the Speaker ID
265
+ * Add conversation context to make responses sound more natural in a dialogue
