Character sets for custom vocabularies and vocabulary filters

For each language Amazon Transcribe supports, there is a specific set of characters Amazon Transcribe can recognize. When you create a custom vocabulary or vocabulary filter, use only the characters listed in your language's character set. If you use unsupported characters, your custom vocabulary or vocabulary filter fails.

Important

Be sure to check that your custom vocabulary file uses only the supported Unicode code points and code point sequences listed within the following character sets.

Many Unicode characters can appear identical in popular fonts, even if they use different code points. Only the code points listed in this guide are supported. For example, the French word déjà can be rendered using precomposed characters (where one Unicode value represents an accented character) or decomposed characters (where two Unicode values represent an accented character, one value for the base character and another for the accent).

• Precomposed version: 0064 00E9 006A 00E0 (renders as déjà)

• Decomposed version: 0064 0065 0301 006A 0061 0300 (renders as déjà)
