<Say>

The <Say> verb reads the supplied text back to the caller. It is useful for text that is difficult to pre-record. The gender and language in which the text will be read is customizable.

Verb Attributes

Attribute
`voice` optional	The attribute `voice` supports: man, woman, alice, Amazon Polly voices by prefixing them with `Polly.`, Amazon Polly Neural voices by prefixing them with `Polly.` and ending them with `-Neural`, Google Cloud voices by prefixing them with `gcloud.`. Polly Neural and Google Wavenet voices are charged a premium price compared to Polly Standard and Google Standard voices. Default is woman for most languages. alice is deprecated and provided for backward compatibility. See below for language specifications on each of these voices.
`loop` optional	The attribute `loop` specifies the number of times a text is to be repeated. If `loop` is set to 0, the text will be continuously repeated until the call is terminated. Default behavior is one repetition.
`language` optional	The attribute `language` allows you to specify the dialect (language and locale) of `voice`. See below for all language specifications.

Noun
`plain text` limit: 4,096 unicode characters	The text that will be read to the caller.

Speech Synthesis Markup Language (SSML)

Speech Synthesis Markup Language (SSML) is an XML-based markup language that provides a standard way to mark up text for synthesized speech.

SSML is usually wrapped within <speak> tags. But, when using SSML with the <Say> verb, you can ignore those <speak> tags. The rest of the SSML tags will be placed inside the <Say> verb.

Below are the supported SSML tags. When using an Amazon Polly voice, please refer to https://docs.aws.amazon.com/polly/latest/dg/supportedtags.html instead.

Tag
`<break>`	A pause in speech. Set the length of the pause with the `time` attribute. Maximum pause time is 10s. Include the unit `s` or `ms` when setting a `time`. The `strength` attribute can also be used for pauses. See below for possible values.
`<emphasis>`	Emphasize words or phrases. This tag changes the rate and volume of speech. More emphasis generates louder and slower speech while less emphasis generates quieter and faster speech. Emphasis can be modified with the `level` attribute. See below for possible values.
`<lang>`	Specify another language for specific words or phrases. Set the language with the `xml:lang` attribute. Possible languages are: `en-US`, `en-GB`, `en-IN`, `en-AU`, `en-CA`, `de-DE`, `es-ES`, `it-IT`, `ja-JP`, `fr-FR` (English, German, Spanish, Italian, Japanese, French).
`<p>`	Add a pause between paragraphs.
`<phoneme>`	Phonetic pronunciation for specified words or phrases. Set the phonetic alphabet to use with the `alphabet` attribute. See below for possible values. In addition, you can use the `ph` attribute to set the phonetic pronunciation to speak. See here for a list of supported symbols.
`<prosody>`	Modify the `volume`, `pitch`, and `rate` of the tagged speech.
`<s>`	Add a pause between sentences.
`<say-as>`	Describe how text should be interpreted. See below for all the possible values of the `interpret-as` attribute of the `<say-as>` tag.
`<sub>`	Pronounce the specified word or phrase as a different word or phrase. Specify the pronunciation to substitute with the `alias` attribute.

`strength` attribute

The strength attribute has the following values. Default is medium.

Value
`none`	No pause. Can be used to remove a pause that would normally occur.

`weak`	Treat adjacent words as if separated by a single comma.
`medium`	Treat adjacent words as if separated by a single comma.
`strong`	Sentence break.
`x-strong`	Paragraph break.

`level` attribute

The level attribute has the following values. Default is moderate.

Value
`strong`	Increase the volume and slow down the speaking rate. Speech is louder and slower.
`moderate`	Increase the volume and slow down the speaking rate, but not as much as `strong`.

`alphabet` attribute

The alphabet attribute has the following values.

Value
`ipa`	The International Phonetic Alphabet (IPA).

'Hello' will be repeated 5 times in Canadian French.

Notes on Usage

There is a 4,096 Unicode character limit on the text
Numbers are spoken, or read, based on context. For example, '234' is read as "two hundred thirty-four", whereas '2 3 4' is read as "two three four".
Short pauses in spoken text are accomplished by inserting punctuations, i.e. commas and periods, in the written text. For longer pauses, place text in a separate <Say> verbs and place a <Pause> verb in between them.
Dates, times, money amounts, and abbreviations may not follow intuitive pronunciations. Test these situations to ensure they are pronounced to your liking.
