  Pronunciation dictionaries are an important component in the process of
speech forced alignment. The accuracy of these dictionaries has a strong effect
on the aligned speech data since they help the mapping between orthographic
transcriptions and acoustic signals. In this paper, I present the creation of a
comprehensive pronunciation dictionary in Spanish (ESPADA) that can be used in
most of the dialect variants of Spanish data. Current dictionaries focus on
specific regional variants, but with the flexible nature of our tool, it can be
readily applied to capture the most common phonetic differences across major
dialectal variants. We propose improvements to current pronunciation
dictionaries as well as mapping other relevant annotations such as
morphological and lexical information. In terms of size, it is currently the
most complete dictionary with more than 628,000 entries, representing words
from 16 countries. All entries come with their corresponding pronunciations,
morphological and lexical tagging, and other relevant information for phonetic
analysis: stress patterns, phonotactics, IPA transcriptions, and more. This
aims to equip socio-phonetic researchers with a complete open-source tool that
enhances dialectal research within socio-phonetic frameworks in the Spanish
language.
