Pronouncingthe titles of classical music and the names of composers and performers is a daunting task for many Americans because so many of the words are foreign to us. Adding to the difficulty is the fact that some of the names that look familiar are not pronounced as we would pronounce them. This dictionary provides some help in the form of pronunciations by a phonetic system devised by E. Douglas Brown of the staff of WOI Radio at Iowa State University. Many of the pronunciations in the dictionary were derived from tape-recorded pronunciations made by foreign nationals who were were speaking their respective native languages.
Prepared primarily for the announcing staff of WOI, the dictionary has been found useful by them and is being made freely available to others who may find it of value. Although imperfect and far from complete, the dictionary, with its 30,000 entries, is the most extensive of its type now available. See the Preface and Pronunciation Conventions for more information. The dictionary includes a PDF file for each letter of the alphabet.
If more than one written pronunciation is given for a word, they are all acceptable, but the first form given is the most common. Not all possible American pronunciations are shown in this dictionary. For example, some speakers only use the sound /ɔ/ when it is followed by /r/ (as in horse /hɔrs/) and use /ɑ/ in all other words that are shown with /ɔ/ in this dictionary, so that they pronounce both caught and cot as /kɑt/.
This dictionary is the first comprehensive description of Shakespearean original pronunciation (OP), enabling practitioners to answer any queries about the pronunciation of individual words. It includes all the words in the First Folio, transcribed using IPA, and provides sound files as an additional aid to pronunciation. It details the main pronunciation evidence in the texts, notably all spelling variants and rhymes. An extensive introduction provides a full account of the aims, evidence, history, and current use of OP in relation to Shakespeare productions as well as other uses. It is an invaluable resource for producers, directors, actors, and others wishing to present Shakespeare's plays or poetry in original pronunciation, as well as for students and academics in the fields of literary criticism and Shakespeare studies more generally.

Note that a pronunciation is provided in brackets after the word above. If you are looking for a spoken pronunciation then you are right that there is none. You will find them on the web, like
dictionary.com.
As of 2.0.5, dictionaries have a firmer format of requiring tab-delimited columns (words, pronunciations, etc), and space-delimited pronunciations to avoid confusions in automatically interpreting dictionary format for phonesets that include numbers like X-SAMPA.
If your dictionary uses spaces as the delimiter between orthography and pronunciations, you can re-encode it with tabs in a text editor that has regex search and replace support. The regex pattern ^(S+)s+ replaced with 1t or $1t, depending on the text editor in question, will replace the first whitespace in every line with a tab.
The list of all unknown words (out of vocabulary words; OOV words) willbe output to a file named oovs_found.txtin the output directory, if you would like to add them to the dictionaryyou are using. To help find any typos in transcriptions, a file namedutterance_oovs.txt will be put in the output directory and will listthe unknown words per utterance.
As part of parsing orthographic transcriptions, punctuation is strippedfrom the ends and beginnings of words, except for the brackets specified in Dictionary and text parsing options. In addition, all words are converted to lowercase so that dictionary lookup is not case-sensitive.
The default compound marker is a hyphen (-).Compound markers are treated similarly to clitic markers, but they are not associated with oneparticular element in the word over another. Instead, they are used to simply split the compound word.For example, merry-go-round willbecome merry go round if the hyphenated form is not in the dictionary.If no words are found on splitting the word based on hyphens or apostrophes,then the word will be treated as a single unit (single unknown word).
The default behavior of the aligner to is to clean up these internal splits and reconstruct the original word. If this is not desirable, you can disable clean up via the --disable_textgrid_cleanup flag (see Configuration).
Up to 2.0.5, words and their transcriptions could be separated by any white space, not just tab. However, given the complexities of parsing probabilistic lexicons with transcription systems like X-SAMPA that use numbers as symbols, we have decided to standardize the column delimiter as tab.
A dictionary for English that has good coverage is the lexicon derivedfrom the LibriSpeech corpus (LibriSpeech lexicon).This lexicon uses the Arpabet transcription format (like the CMU Pronouncing Dictionary).
The Prosodylab-aligner has two preconstructed dictionaries as well, onefor English (Prosodylab-aligner English dictionary)and one for Quebec French (Prosodylab-aligner French dictionary), also see MFA dictionaries for a list of supported dictionaries.
See the page on Generate pronunciations for words (mfa g2p) for how to use G2P models to generate a dictionaryfrom our pretrained models or how to generate pronunciation dictionaries from orthographies.
The three columns should be separated by tabs, with the first column corresponding the orthographic form, the second to the pronunciation probability between 0.01 and 1.0, and the final column the space-delimited pronunciation.
The most likely probability for a word is set to 1.0 in the algorithm implemented in Add probabilities to a dictionary (mfa train_dictionary).While this means that the sum of probabilities per word is greater than 1, it does not penalize words for havingmultiple pronunciations, and these probabilities are converted to log costs in the eventual weighted FST.
As part of modeling pronunciation probabilities, probabilities of silence before and after a given pronunciation can be estimated as well. As an example, with pronunciations of the English word the, we might have one that is a full version [ i] and a more reduced version [ ə]. While the the more reduced version will be the more likely variant overall, the full version will likely have a higher probabilities following or preceding silence.
The first float column is the probability of the pronunciation, the next float is the probability of silence following the pronunciation, and the final two floats are correction terms for preceding silence and non-silence. Given that each entry in a dictionary is independent and there is no way to encode information about the preceding context, the correction terms are calculated as how much more common was silence or non-silence compared to what we would expect factoring out the likelihood of silence from the previous word. More details are found in get_prons.sh and the related paper.
There are two special phones that can be used for annotations that are not speech, sil and spn. The sil phone is usedto model silence, and the spn phone is used to model unknown words. If you have annotations for non-speech vocalizations that aresimilar to silence like breathing or exhalation, you can use the sil phone to align those. You can use the spn phoneto align annotations like laughter, coughing, etc.
Often in spontaneous speech, speakers will produce truncated or cut-off words of the following word/words. To help model this specific case, using the flag --use_cutoff_model will enable a mode where pronunciations are generated for cutoff words matching one of the following criteria:
The cutoff word matches the pattern of start_bracket(cutoffhes)[-_](word)end_bracket, where start and end brackets are defined in brackets (Dictionary and text parsing options). The word will be used in place of the following word above, but needs to be present in the dictionary, otherwise the target word for the cutoff will default back to the following word.
In addition to the basic capabilities, specifying a phone set can aid in creating acoustic models that are better suited to the particular phones, with better contextual questions dependent on the place and manner of articulation for triphone modeling.
Alias tags are supported by all models excluding eleven_turbo_v2_5. Phoneme tags only work with the modelseleven_turbo_v2 and eleven_monolingual_v1. If you use phoneme tags withother models, they will silently skip the word.
Before you begin, make sure you have installed the necessary SDKs and libraries. You will need the ElevenLabs SDK for the updating pronunciation dictionary and using text-to-speech conversion. You can install it using pip:
In the following snippet, we start by adding rules from a file and get the uploaded result. Finally, we generate and play two different text-to-speech audio to compare the custom pronunciation dictionary.
To remove rules from a pronunciation dictionary, we can simply call remove_rules_from_the_pronunciation_dictionary method in the pronunciation dictionary module. In the following snippet, we start by removing rules based on the rule string and get the updated result. Finally, we generate and play another text-to-speech audio to test the difference. In the example, we take pronunciation dictionary version id from remove_rules_from_the_pronunciation_dictionary response because every changes to pronunciation dictionary will create a new version, so we need to use the latest version returned from the response. The old version also still available.
