Portuguese expressive voices

Speaking styles

Table 1 provides examples of each available style for the <express-as> element for Portuguese. To demonstrate the effect of the styles, the table provides two samples for each example. The first sample speaks the text with the default pt-BR_LucasExpressive voice. The second sample speaks the same text with the same voice but with the indicated style. A request that uses the <express-as> element fails if the style is not one of the supported values or is omitted from the element.

Speaking styles
Style	Example input text	Audio sample
`cheerful`	`"Claro! Que ótima notícia!"`
	`"<express-as style="cheerful"> Claro! Que ótima notícia! </express-as>"`
`empathetic`	`"Infelizmente, não vou conseguir te ajudar nisso."`
	`"<express-as style="empathetic"> Infelizmente, não vou conseguir te ajudar nisso. </express-as>"`
`neutral`	`"O clima é muito seco no outono."`
	`"<express-as style="neutral"> O clima é muito seco no outono. </express-as>"`
`uncertain`	`"Desculpe, poderia repetir seu número novamente?"`
	`"<express-as style="uncertain"> Desculpe, poderia repetir seu número novamente? </express-as>"`

Emphasizing interjections

For Portuguese, we currently support the following interjections - ah, aham, ahn, eh, hum and uhum.

Table 2 lists the interjections that the service recognizes and provides examples of how they are pronounced in synthesized speech. The samples use the pt-BR_LucasExpressive voice. The table shows the primary spelling of each interjection. The service recognizes alternative spellings for some of the interjections. For example, eh and ehh produce the same sound, as do hum and humm. However, the service produces slightly different pronunciations for other alternative spellings, such as aah and eeh.

Interjections that are emphasized
Interjection	Example sentence	Audio sample
`ah`	`"Ah, não tem problema algum!"`
`aham`	`"Aham, já encaminharemos para você imediatamente."`
`ahn`	`"Ahn, poderia aguardar na linha por favor?"`
`eh`	`"Eh, só um segundinho que vou checar com meu gerente."`
`hum`	`"Hum, não tenho muita certeza disso."`
`uhum`	`"Uhum, seu pacote será entregue até o final do dia!"`

Enabling or disabling interjections with SSML

For Portuguese, all interjections are enabled by default, and it is not possible to enable/disable these interjections.

Usage notes for interjections

Keep the following in mind when using interjections:

The neutral style does not emphasize interjections to the extent of the default expressive voice or the other styles.
