synthesize(body=None, x__xgafv=None)
Synthesizes speech synchronously: receive results after all text input
synthesize(body=None, x__xgafv=None)
Synthesizes speech synchronously: receive results after all text input
has been processed.
Args:
body: object, The request body.
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.
"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).
"text": "A String", # The raw text to be synthesized.
},
"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. 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", # Required. The language (and potentially 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". 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. 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 audio byte stream.
"effectsProfileId": [ # Optional. Input only. 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, # Optional. The synthesis sample rate (in hertz) for this audio. When this is
# specified in SynthesizeSpeechRequest, 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. Input only. 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. Input only. 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. Input only. 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 encodings that are wrapped in containers (e.g. MP3, OGG_OPUS).
# 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.
