<pre>Synthesizes speech synchronously: receive results after all text input

has been processed.
|
|
|
|
Args:
|
|
body: object, The request body. (required)
|
|
The object takes the form of:
|
|
|
|
{ # The top-level message sent by the client for the `SynthesizeSpeech` method.
|
|
"input": { # Contains text input to be synthesized. Either `text` or `ssml` must be # Required. The Synthesizer requires either plain text or SSML as input.
|
|
# supplied. Supplying both or neither returns
|
|
# google.rpc.Code.INVALID_ARGUMENT. The input size is limited to 5000
|
|
# characters.
|
|
"text": "A String", # The raw text to be synthesized.
|
|
"ssml": "A String", # The SSML document to be synthesized. The SSML document must be valid
|
|
# and well-formed. Otherwise the RPC will fail and return
|
|
# google.rpc.Code.INVALID_ARGUMENT. For more information, see
|
|
# [SSML](/speech/text-to-speech/docs/ssml).
|
|
},
|
|
"voice": { # Description of which voice to use for a synthesis request. # Required. The desired voice of the synthesized audio.
|
|
"ssmlGender": "A String", # The preferred gender of the voice. Optional; if not set, the service will
|
|
# choose a voice based on the other parameters such as language_code and
|
|
# name. Note that this is only a preference, not requirement; if a
|
|
# voice of the appropriate gender is not available, the synthesizer should
|
|
# substitute a voice with a different gender rather than failing the request.
|
|
"languageCode": "A String", # The language (and optionally also the region) of the voice expressed as a
|
|
# [BCP-47](https://www.rfc-editor.org/rfc/bcp/bcp47.txt) language tag, e.g.
|
|
# "en-US". Required. This should not include a script tag (e.g. use
|
|
# "cmn-cn" rather than "cmn-Hant-cn"), because the script will be inferred
|
|
# from the input provided in the SynthesisInput. The TTS service
|
|
# will use this parameter to help choose an appropriate voice. Note that
|
|
# the TTS service may choose a voice with a slightly different language code
|
|
# than the one selected; it may substitute a different region
|
|
# (e.g. using en-US rather than en-CA if there isn't a Canadian voice
|
|
# available), or even a different language, e.g. using "nb" (Norwegian
|
|
# Bokmal) instead of "no" (Norwegian)".
|
|
"name": "A String", # The name of the voice. Optional; if not set, the service will choose a
|
|
# voice based on the other parameters such as language_code and gender.
|
|
},
|
|
"audioConfig": { # Description of audio data to be synthesized. # Required. The configuration of the synthesized audio.
|
|
"audioEncoding": "A String", # Required. The format of the requested audio byte stream.
|
|
"effectsProfileId": [ # An identifier which selects 'audio effects' profiles that are applied on
|
|
# (post synthesized) text to speech.
|
|
# Effects are applied on top of each other in the order they are given.
|
|
# See
|
|
#
|
|
# [audio-profiles](https:
|
|
# //cloud.google.com/text-to-speech/docs/audio-profiles)
|
|
# for current supported profile ids.
|
|
"A String",
|
|
],
|
|
"sampleRateHertz": 42, # The synthesis sample rate (in hertz) for this audio. Optional. If this is
|
|
# different from the voice's natural sample rate, then the synthesizer will
|
|
# honor this request by converting to the desired sample rate (which might
|
|
# result in worse audio quality), unless the specified sample rate is not
|
|
# supported for the encoding chosen, in which case it will fail the request
|
|
# and return google.rpc.Code.INVALID_ARGUMENT.
|
|
"pitch": 3.14, # Optional speaking pitch, in the range [-20.0, 20.0]. 20 means increase 20
|
|
# semitones from the original pitch. -20 means decrease 20 semitones from the
|
|
# original pitch.
|
|
"speakingRate": 3.14, # Optional speaking rate/speed, in the range [0.25, 4.0]. 1.0 is the normal
|
|
# native speed supported by the specific voice. 2.0 is twice as fast, and
|
|
# 0.5 is half as fast. If unset(0.0), defaults to the native 1.0 speed. Any
|
|
# other values < 0.25 or > 4.0 will return an error.
|
|
"volumeGainDb": 3.14, # Optional volume gain (in dB) of the normal native volume supported by the
|
|
# specific voice, in the range [-96.0, 16.0]. If unset, or set to a value of
|
|
# 0.0 (dB), will play at normal native signal amplitude. A value of -6.0 (dB)
|
|
# will play at approximately half the amplitude of the normal native signal
|
|
# amplitude. A value of +6.0 (dB) will play at approximately twice the
|
|
# amplitude of the normal native signal amplitude. Strongly recommend not to
|
|
# exceed +10 (dB) as there's usually no effective increase in loudness for
|
|
# any value greater than that.
|
|
},
|
|
}
|
|
|
|
x__xgafv: string, V1 error format.
|
|
Allowed values
|
|
1 - v1 error format
|
|
2 - v2 error format
|
|
|
|
Returns:
|
|
An object of the form:
|
|
|
|
{ # The message returned to the client by the `SynthesizeSpeech` method.
|
|
"audioContent": "A String", # The audio data bytes encoded as specified in the request, including the
|
|
# header (For LINEAR16 audio, we include the WAV header). Note: as
|
|
# with all bytes fields, protobuffers use a pure binary representation,
|
|
# whereas JSON representations use base64.
