Typhoon2-Audio

Typhoon2-Audio is an end-to-end speech-to-speech model architecture capable of processing audio, speech, and text inputs and generating both text and speech outputs simultaneously. It is optimized specifically for Thai, but it also supports English.

Model Description

• Model type: The LLM is based on Typhoon2 LLM.
• Requirement: Python==3.10 & transformers==4.52.2 & fairseq==0.12.2 & flash-attn
• Primary Language(s): Thai 🇹🇭 and English 🇬🇧
• License-Speech-Input & LLM: Llama 3.1 Community License

Installation

pip install pip==24.0
pip install transformers==4.45.2
pip install fairseq==0.12.2 # fairseq required pip==24.0 to install & only worked only on python 3.10
pip install flash-attn

Usage

Load Model

import torch
from transformers import AutoModel
model = AutoModel.from_pretrained(
    "scb10x/llama3.1-typhoon2-audio-8b-instruct",
    torch_dtype=torch.float16, 
    trust_remote_code=True
)
model.to("cuda")

Inference - Single turn example

conversation = [
    {"role": "system", "content": "You are a helpful female assistant named ไต้ฝุ่น."},
    {
        "role": "user",
        "content": [
            {
                "type": "audio",
                "audio_url": "examples/tmp-2860cd0a094b64043226167340af03a3.wav",
            },
            {"type": "text", "text": "Transcribe this audio"},
        ],
    },
]
x = model.generate(
    conversation=conversation,
    max_new_tokens=500,
    do_sample=True,
    num_beams=1,
    top_p=0.9,
    repetition_penalty=1.0,
    length_penalty=1.0,
    temperature=0.7,
)
# x => x['text'] (text), x['audio'] (numpy array)
# to save the audio output
# import soundfile as sf
# sf.write("examples/speechout.wav", x["audio"]["array"], x["audio"]["sampling_rate"])

Inference - Multi turn example

conversation_multi_turn = [
    {
        "role": "system",
        "content": "You are a helpful female assistant named ไต้ฝุ่น. Respond conversationally to the speech provided in the language it is spoken in.",
    },
    {
        "role": "user",
        "content": [
            {
                "type": "audio",
                "audio_url": "examples/tmp-2860cd0a094b64043226167340af03a3.wav",
                # บอกชื่อเมืองใหญ่ๆในอเมริกามาให้หน่อยสิ -- "List some names of US cities"
            },
            {
                "type": "text",
                "text": "",
            },
        ],
    },
    {
        "role": "assistant",
        "content": [
            {
                "type": "text",
                "text": "โอเคค่ะ, ฉันจะบอกชื่อเมืองใหญ่ๆ ในอเมริกาให้คุณฟัง:\n\n1. นิวยอร์ก\n2. ลอสแอนเจลิส\n3. ชิคาโก\n4. ฮิวสตัน\n5. ฟิลาเดลเฟีย\n6. บอสตัน\n7. ซานฟรานซิสโก\n8. วอชิงตัน ดี.ซี. (Washington D.C.)\n9. แอตแลนต้า\n10. ซีแอตเทิล\n\nถ้าคุณต้องการข้อมูลเพิ่มเติมหรือมีคำถามอื่นๆ กรุณาถามได้เลยค่ะ'",
            },
        ],
    },
    {
        "role": "user",
        "content": [
            {
                "type": "audio",
                "audio_url": "examples/tmp-2284cd76e1c875525ff75327a2fc3610.wav",
                # แล้วถ้าเป็นประเทศอังกฤษล่ะ -- "How about the UK"

            },
        ],
    },
]
x = model.generate(conversation=conversation_multi_turn)
# x => x['text'] (text), x['audio'] (numpy array)
# to save the audio output
# import soundfile as sf
# sf.write("examples/speechout.wav", x["audio"]["array"], x["audio"]["sampling_rate"])

TTS functionality

y = model.synthesize_speech("Hello, my name is ไต้ฝุ่น I am a language model specialized in Thai")
# y => numpy array

Evaluation Results

• 1) Audio and Speech Understanding

• 2) Speech-to-Speech Evaluation

• 2.1) Content Generation

• 2.2) Speech Quality

*Note that Llama-Omni does not generate Thai text/speech, so it has low CER and high UTMOS due to the outputs being English.

Intended Uses & Limitations

This model is experimental and may not always follow human instructions accurately, making it prone to generating hallucinations. Additionally, the model lacks moderation mechanisms and may produce harmful or inappropriate responses. Developers should carefully assess potential risks based on their specific applications.
