+# Download a small subset from HuggingFace
+# These are curated samples for the 6 OpenAI-compatible voice types:
+# - alloy: neutral/balanced
+# - echo: male, clear
+# - fable: expressive/storyteller
+# - onyx: deep male
+# - nova: female, warm
+# - shimmer: female, soft
+
+# Using LibriVox/LibriSpeech samples (public domain audiobooks)
+# Format: Speaker reads a passage, we take a clean 3-10 second clip

+cat << 'EOF'
+Voice samples need to be:
+- 3-10 seconds of clear speech
+- Single speaker, no background noise
+- WAV format (16kHz or higher)
+- With exact transcript
+
+Recommended sources:
+1. LibriSpeech test-clean: https://www.openslr.org/12
+2. VCTK: https://datashare.ed.ac.uk/handle/10283/3443
+3. LJ Speech: https://keithito.com/LJ-Speech-Dataset/
+
+For now, using Qwen's demo sample for all voices.
+To add distinct voices, place WAV files in voices/samples/ and update
+config/voice_to_speaker.yaml with paths and transcripts.
+
+Example voice_to_speaker.yaml entry:
+  alloy:
+    ref_audio: voices/samples/alloy.wav
+    ref_text: "The exact words spoken in the audio file."
+    language: English
