Lexicons for Speech Synthesis

Customizing Pronunciation with Lexicons

Lexicons are used in speech synthesis to override the default pronunciation of specific words. This is useful for words that are pronounced differently in different contexts, such as the word "lead" (which can be pronounced as the present tense verb or as a noun).

Examples of Lexicon Use

Here are some examples of how lexicons can be used with speech synthesis engines:

• To specify the correct pronunciation of acronyms or industry-specific terms
• To change the pronunciation of foreign words or names
• To create custom voices with unique pronunciations

Lexicon Structure

Lexicons are typically stored in text files, with each line containing the following information:

1. The original spelling of the word
2. The desired pronunciation (in phonetic symbols)

Considerations

When creating custom lexicons, it's important to consider the following:

• The speech synthesis engine's support for lexicons
• The accuracy and consistency of the pronunciation data
• The size and complexity of the lexicon
