+# Audio Transcription
+
+RubyLLM makes it easy to transcribe audio content using AI models. This guide covers how to convert speech to text using transcription models.
+
+## Basic Transcription
+
+The simplest way to convert speech to text is using the global `transcribe` method with only a local audio file path:
+
+```ruby
+# Transcribe an audio file
+text = RubyLLM.transcribe("meeting.wav")
+
+# Print the transcribed text
+puts text
+```
+
+This method automatically uses the default transcription model (whisper-1) to convert the audio file to text.
+
+## Specifying a Language
+
+If you know the language in the audio, you can provide a hint to improve transcription accuracy:
+
+```ruby
+# Transcribe Spanish audio
+spanish_text = RubyLLM.transcribe("entrevista.mp3", language: "Spanish")
+```
+
+## Choosing Models
+
+You can specify which model to use for transcription:
+
+```ruby
+# Use a specific model
+text = RubyLLM.transcribe(
+  "interview.mp3",
+  model: "whisper-1"
+)
+```
+
+You can configure the default transcription model globally:
+
+```ruby
+RubyLLM.configure do |config|
+  config.default_transcription_model = "whisper-1"
+end
+```
+
+## Working with Large Files
+
+For longer audio files, be aware of potential timeout issues. You can set a global timeout in your application configuration:
+
+```ruby
+RubyLLM.configure do |config|
+  # Set a longer timeout for large files (in seconds)
+  config.request_timeout = 300
+end
+```
+
+Currently, RubyLLM doesn't support per-request timeout configuration. For handling very large files, you may need to increase the global timeout or consider breaking up the audio into smaller segments.
+
