Query: MoBoAligner: a Neural Alignment Model for Non-autoregressive TTS with
  Monotonic Boundary Search   To speed up the inference of neural speech synthesis, non-autoregressive
models receive increasing attention recently. In non-autoregressive models,
additional durations of text tokens are required to make a hard alignment
between the encoder and the decoder. The duration-based alignment plays a
crucial role since it controls the correspondence between text tokens and
spectrum frames and determines the rhythm and speed of synthesized audio. To
get better duration-based alignment and improve the quality of
non-autoregressive speech synthesis, in this paper, we propose a novel neural
alignment model named MoboAligner. Given the pairs of the text and mel
spectrum, MoboAligner tries to identify the boundaries of text tokens in the
given mel spectrum frames based on the token-frame similarity in the neural
semantic space with an end-to-end framework. With these boundaries, durations
can be extracted and used in the training of non-autoregressive TTS models.
Compared with the duration extracted by TransformerTTS, MoboAligner brings
improvement for the non-autoregressive TTS model on MOS (3.74 comparing to
FastSpeech's 3.44). Besides, MoboAligner is task-specified and lightweight,
which reduces the parameter number by 45% and the training time consuming by
30%.
