It is possible to include Spanish voices of Polly?

Thanks in advance!

It seems that is already implemented by language=NULL option in list_voices function according to Issue #5

Nevertheless I got

> list_voices(language = NULL)
list()
Warning messages:
1: In pollyHTTP(action = "voices", verb = "GET", query = query, ...) :
  Forbidden (HTTP 403).
2: In structure(out[["Voices"]], NextToken = out[["NextToken"]]) :
  Calling 'structure(NULL, *)' is deprecated, as NULL cannot have attributes.
  Consider 'structure(list(), *)' instead.

Commit 7542d60 effectively adds Spanish capability.

[Antoine Sachet]

This is correct, list_voices(language = NULL) will list all available voices.

However, I would not say it "adds Spanish capability", as the more direct way to list Spanish voices is to use language = "es-ES" (Castilian Spanish) or "es-US" (US Spanish ) or "es-MX" (Mexican Spanish).

For example:

aws.polly::list_voices(language = "es-ES")
#>   AdditionalLanguageCodes Gender       Id LanguageCode      LanguageName
#> 1                      NA Female    Lucia        es-ES Castilian Spanish
#> 2                      NA   Male  Enrique        es-ES Castilian Spanish
#> 3                      NA Female Conchita        es-ES Castilian Spanish
#>       Name SupportedEngines
#> 1    Lucia         standard
#> 2  Enrique         standard
#> 3 Conchita         standard

FYI the error you get (HTTP 403 - Forbidden) is a permission issue: make sure the AWS account or role you use has permission to list voices.
