+
+[Demo Talk](https://user-images.githubusercontent.com/1991296/206805012-48e71cc2-588d-4745-8798-c1c70ea3b40d.mp4)
+
+Web version: [examples/talk.wasm](/examples/talk.wasm)
+
+## Building
+
+The `talk` tool depends on SDL2 library to capture audio from the microphone. You can build it like this:
+
+```bash
+# Install SDL2 on Linux
+sudo apt-get install libsdl2-dev
+
+# Install SDL2 on Mac OS
+brew install sdl2
+
+# Build the "talk" executable
+make talk
+
+# Run it
+./talk -p Santa
+```
+
+To run this, you will need a ggml GPT-2 model: [instructions](https://github.com/ggerganov/ggml/tree/master/examples/gpt-2#downloading-and-converting-the-original-models)
+
+Alternatively, you can simply download the smallest ggml GPT-2 117M model (240 MB) like this:
+
+```
+wget --quiet --show-progress -O models/ggml-gpt-2-117M.bin https://ggml.ggerganov.com/ggml-model-gpt-2-117M.bin
+```
