Apple Machine Learning - dMel: Speech Tokenization Made Simple

“Large language models have revolutionized natural language processing by leveraging self-supervised pretraining on vast textual data. Inspired by this success, researchers have investigated complicated speech tokenization methods to discretize continuous speech signals so that language modeling techniques can be applied to speech data… Here we show that discretizing mel-filterbank channels into discrete intensity bins produces a simple representation (dMel), that performs better than other existing speech tokenization methods.”

Postgres updates - pg_builder and pg_wrapper 3.0 released

“pg_builder is a query builder for Postgres backed by a partial PHP reimplementation of PostgreSQL's own SQL parser. It supports almost all syntax available in Postgres 17 for SELECT (and VALUES), INSERT, UPDATE, DELETE, and MERGE queries… pg_wrapper provides converters for PostgreSQL data types and an object-oriented wrapper for PHP's native pgsql extension that uses these converters. Conversion of query result fields is done automatically using database metadata, query parameters may require specifying type.”
