Quick Start
TTA model
from auden.auto.auto_model import AutoModel
# 1) Load a model checkpoint directory (contains config.json + weights)
model_dir = "AudenAI/auden-tta-m10" # or any exported directory / HF repo id
model = AutoModel.from_pretrained(model_dir)
model = model.to("cuda")
model.eval()
# 2) Prepare input features (x, x_lens). If you have raw audio, you can use
# model.speech_encoder.extract_feature(wav) to get (x, x_lens).
x, x_lens = ... # Tensor shapes: (B, T, F), (B,)
inputs = (x, x_lens)
# Alternatively, you can pass WAV inputs directly:
# - List of WAV paths (str):
# inputs = ["/abs/a.wav", "/abs/b.wav"]
# - List of mono waveforms (Tensor/ndarray), 16 kHz:
# inputs = [torch.randn(16000*5), torch.randn(16000*3)]
# 3a) Transcribe (RNNT greedy)
out = model.generate(inputs, task="transcribe", blank_penalty=0.0, return_timestamps=False)
print(out["hypotheses"]) # list[str]
# 3b) Translate (attention beam search). Language can be a single str or a list[str] per utterance
out = model.generate(
inputs,
task="translate",
beam_size=5,
source_language=["zh"] * x.size(0),
target_language=["en"] * x.size(0),
)
print(out["hypotheses"]) # list[str]
print(out["source_language"]) # list[str], model-predicted or provided
print(out["target_language"]) # list[str], model-predicted or provided
# 3c) Align (audio-text similarity)
texts = ["hello world", "good morning"]
out = model.generate(inputs, task="align", texts=texts)
print(out["similarities"]) # (B, len(texts))
print(out["audio_emb"]) # (B, emb_dim)
print(out["text_emb"]) # (B, emb_dim)TTA encoder
from auden.auto.auto_model import AutoModel
encoder = AutoModel.from_pretrained("AudenAI/auden-encoder-tta-m10")
encoder = encoder.to("cuda")
# 2) Prepare input features (x, x_lens). If you have raw audio, you can use
# encoder.extract_feature(wav) to get (x, x_lens).
x, x_lens = ... # Tensor shapes: (B, T, F), (B,)
encoder_output = encoder(x, x_lens)
print(encoder_output["encoder_out"]) # (B, T//4, D)
print(encoder_output["encoder_out_lens"]) # (B)π Model Characteristics

β οΈ Limitations
- Performance depends on audio quality and recording conditions.
- For long-form audio, chunking and post-processing might be required for optimal performance.
- Not designed for safety-critical applications.
