Query: Almost-unsupervised Speech Recognition with Close-to-zero Resource Based
  on Phonetic Structures Learned from Very Small Unpaired Speech and Text Data   Producing a large amount of annotated speech data for training ASR systems
remains difficult for more than 95% of languages all over the world which are
low-resourced. However, we note human babies start to learn the language by the
sounds of a small number of exemplar words without hearing a large amount of
data. We initiate some preliminary work in this direction in this paper. Audio
Word2Vec is used to obtain embeddings of spoken words which carry phonetic
information extracted from the signals. An autoencoder is used to generate
embeddings of text words based on the articulatory features for the phoneme
sequences. Both sets of embeddings for spoken and text words describe similar
phonetic structures among words in their respective latent spaces. A mapping
relation from the audio embeddings to text embeddings actually gives the
word-level ASR. This can be learned by aligning a small number of spoken words
and the corresponding text words in the embedding spaces. In the initial
experiments only 200 annotated spoken words and one hour of speech data without
annotation gave a word accuracy of 27.5%, which is low but a good starting
point.
