export INPUT_WAV=/path/to/input.wav
export OUTPUT_WAV=/path/to/output.wav

ASR (audio -> text)

./llama-liquid-audio-cli -m $CKPT/LFM2.5-Audio-1.5B-Q40.gguf -mm $CKPT/mmproj-LFM2.5-Audio-1.5B-Q40.gguf -mv $CKPT/vocoder-LFM2.5-Audio-1.5B-Q40.gguf --tts-speaker-file $CKPT/tokenizer-LFM2.5-Audio-1.5B-Q40.gguf -sys "Perform ASR." --audio $INPUT_WAV

TTS (text -> audio)

./llama-liquid-audio-cli -m $CKPT/LFM2.5-Audio-1.5B-Q40.gguf -mm $CKPT/mmproj-LFM2.5-Audio-1.5B-Q40.gguf -mv $CKPT/vocoder-LFM2.5-Audio-1.5B-Q40.gguf --tts-speaker-file $CKPT/tokenizer-LFM2.5-Audio-1.5B-Q40.gguf -sys "Perform TTS." -p "Hi, how are you?" --output $OUTPUT_WAV

Interleaved (audio/text -> audio + text)

./llama-liquid-audio-cli -m $CKPT/LFM2.5-Audio-1.5B-Q40.gguf -mm $CKPT/mmproj-LFM2.5-Audio-1.5B-Q40.gguf -mv $CKPT/vocoder-LFM2.5-Audio-1.5B-Q40.gguf --tts-speaker-file $CKPT/tokenizer-LFM2.5-Audio-1.5B-Q40.gguf -sys "Respond with interleaved text and audio." --audio $INPUTWAV --output $OUTPUTWAV

Server

Start server

export CKPT=/path/to/LFM2.5-Audio-1.5B-GGUF
./llama-liquid-audio-server -m $CKPT/LFM2.5-Audio-1.5B-Q40.gguf -mm $CKPT/mmproj-LFM2.5-Audio-1.5B-Q40.gguf -mv $CKPT/vocoder-LFM2.5-Audio-1.5B-Q40.gguf --tts-speaker-file $CKPT/tokenizer-LFM2.5-Audio-1.5B-Q40.gguf
