<b>Abstract.</b>
Large-scale diffusion models have shown outstanding generative abilities
across multiple modalities including images, videos, and audio. However,
text-to-speech (TTS) systems typically involve domain-specific modeling
factors (e.g., phonemes and phoneme-level durations) to ensure precise
temporal alignments between text and speech, which hinders the efficiency
and scalability of diffusion models for TTS. In this work, we present an
efficient and scalable Diffusion Transformer (DiT) that utilizes off-the-shelf
pre-trained text and speech encoders. Our approach addresses the challenge
of text-speech alignment via cross-attention mechanisms with the prediction
of the total length of speech representations. To achieve this, we enhance
the DiT architecture to suit TTS and improve the alignment by incorporating
semantic guidance into the latent space of speech. We scale the training dataset
and the model size to 82K hours and 790M parameters, respectively. Our extensive
experiments demonstrate that the large-scale diffusion model for TTS without
domain-specific modeling not only simplifies the training pipeline but also
yields superior or comparable zero-shot performance to state-of-the-art TTS
models in terms of naturalness, intelligibility, and speaker similarity. Our
speech samples are available at

<b>An overview of DiTTo-TTS</b>. (<i>middle</i>) The LDM backbone is trained to
denoise a span-masked noisy segment given its contextual counterpart, without utilizing
phoneme and phoneme-level duration (see <b>Section 3.1</b>).
(<i>left</i>) The inner structure of the DiT block incorporates multi-head cross-attention
with global AdaLN (see <b>Section 3.3</b>).
(<i>right</i>)The speech length predictor is based on causal transformer blocks (see <b>Section 3.2</b>).
Both DiT blocks and the speech length predictor employ cross-attention to condition on text representation.
Additionally, DiT blocks utilize AdaLN with the mean-pooled text embedding.
'<b>+</b>' denotes addition, and '<b>c</b>' represents concatenation.
'<b>text</b>' in sky blue oval represents the embedding from text encoder.
The red line indicates a long skip connection between the states before and after the DiT blocks.
The effectiveness of our design choices is demonstrated in our architecture search (see <b>Section 6.1</b>).

Zero-Shot TTS (LibriSpeech)
</h2>
<p>
Through in-context learning, DiTTo-TTS produces speech using a
reference audio and its corresponding text. We represent
<span style="color: #8fbddf; font-weight: bold"
>the prompt in blue</span
>, and
<span style="color: #9fde83; font-weight: bold"
>the generated audio in green</span
>. The resulting speech closely resembles the reference in
voice, background noise, and speaking style. When dividing
prompts into 3-second segments, the audio boundaries may not
always end in silence and could sometimes cut off words midway.
For further details, please see <b>English-only Evaluation</b> part in <b>Section 5.1</b> of our paper.
When you click on "Show baselines", you can see the ground truth
and baseline audio, etc. YourTTS, Vall-E, and CLaM-TTS audios are brought
from YourTTS demo<sup><a href="#footnote1-1">1</a></sup>,

Speech Diversity
</h2>
<p>
DiTTo-TTS can synthesize speech with diverse <b>prosody and timbre</b>,
and even <b>environmental background sounds</b>, from <b>various speakers</b>
when generated without a prompt. First three text scripts are from Gigaspeech
test set, and the last four are brought from
Vall-E demo<sup><a href="#footnote6-1">1</a></sup>.
