`ssml` Tags

The SSML input to synthesize an audio output. If you want to follow W3 standards, the ssml field must be used and not the text field. Refer here to know more about SSML Inputs.

SSML Tag	Description
`<prosody>`	Controls the pitch, rate, and volume of speech.
`<say-as>`	Defines how the enclosed text should be spoken (e.g., as a number, date, etc.).
`<sub>`	Substitutes one word or phrase for another when speaking.
`<break>`	Adds a pause in speech for a specified duration.
`<p>`	Indicates a paragraph break, resulting in a pause.
`<s>`	Represents a sentence break, adding a pause.
`<speak>`	The root tag that defines the speech content.
`<voice>`	Specifies which voice to use for speech (e.g., male, female).

`speed`

The speech rate of the audio file. Allows values: from 0.5 (slowest speed rate) up to 1.5 (fastest speed rate). Note: By default, speed = 1 (normal speed). For Example:

curl --location --request POST 'https://revapi.reverieinc.com/' \
--header 'REV-API-KEY: <YOUR API KEY>' \
--header 'REV-APP-ID: <YOUR APP-ID>' \
--header 'REV-APPNAME: tts' \
--header 'speaker: hi_female' \
--header 'Content-Type: application/json' \
--data-raw '{
	"text": ["भारत मेरा देश है। मेरी कंपनी का नाम रेवेरी लैंग्वेज टेक्नोलॉजीज है।" ], 
	"speed": 1, 
}'

</CodeGroup>

### `pitch` 
Speaking pitch, in the range Allows values: from -3 up tp 3. 3 indicates an increase of 3 semitones from the original pitch. -3 indicates a decrease of 3 semitones from the original pitch. Note: By default, the pitch = 0 (zero)

**For Example**: 
<CodeGroup>
```bash cURL
curl --location --request POST 'https://revapi.reverieinc.com/' \
--header 'REV-API-KEY: <YOUR API KEY>' \
--header 'REV-APP-ID: <YOUR APP-ID>' \
--header 'REV-APPNAME: tts' \
--header 'speaker: hi_female' \
--header 'Content-Type: application/json' \
--data-raw '{
	"text": ["भारत मेरा देश है। मेरी कंपनी का नाम रेवेरी लैंग्वेज टेक्नोलॉजीज है।" ], 
	"pitch": -3, 
}'

`sample_rate`

The sampling rate (in hertz) to synthesize the audio output. Refer to Supporting Sampling Rate, to know the supporting audio sample rates. Note: By default, the sample_rate = 22050 Hz (22.05kHz) For Example:

curl --location --request POST 'https://revapi.reverieinc.com/' \
--header 'REV-API-KEY: <YOUR API KEY>' \
--header 'REV-APP-ID: <YOUR APP-ID>' \
--header 'REV-APPNAME: tts' \
--header 'speaker: hi_female' \
--header 'Content-Type: application/json' \
--data-raw '{
	"text": ["भारत मेरा देश है। मेरी कंपनी का नाम रेवेरी लैंग्वेज टेक्नोलॉजीज है।" ], 
	"sample_rate": 22050, 
}'

`format`

The speech audio format to generate the audio file. Refer to Supporting Audio Formats, to know the supporting audio formats. Note: By default, the format = WAV For Example:

curl --location --request POST 'https://revapi.reverieinc.com/' \
--header 'REV-API-KEY: <YOUR API KEY>' \
--header 'REV-APP-ID: <YOUR APP-ID>' \
--header 'REV-APPNAME: tts' \
--header 'speaker: hi_female' \
--header 'Content-Type: application/json' \
--data-raw '{
	"text": ["भारत मेरा देश है। मेरी कंपनी का नाम रेवेरी लैंग्वेज टेक्नोलॉजीज है।" ], 
	"format": wav, 
}'
