Time offsets (timestamps) are now available.
enableWordTimeOffsets parameter to true in your request configuration
and Cloud Speech-to-Text will include time offset values for the beginning and
end of each spoken word that is recognized in the audio for your request.
For more information, see
Time offsets (timestamps).
Cloud Speech-to-Text has added recognition support for 30 new languages. For a complete list of all supported languages, see the language support reference.
The limit on the length of audio that you can send with an asynchronous recognition request has been increased from ~80 to ~180 minutes. For information on Cloud Speech-to-Text limits, see the quotas & limits. For more information on asynchronous recognition requests, see the transcribing long audio files guide.

Release of Cloud Speech-to-Text v1.
v1beta1 release of Cloud Speech-to-Text
has been deprecated. The
continues to be available for a period of time as defined in the
terms of service.
To avoid being impacted when the
is discontinued, replace references to
v1beta1 in your code with
v1 and update your code with valid
v1 API names and values.
language_code is now required with requests to Cloud Speech-to-Text. Requests
with a missing or invalid
language_code will return an error.
(Pre-release versions of the API used
en-US if the
language_code was omitted from the request.)
SyncRecognize is renamed to
v1beta1/speech:syncrecognize is renamed to
v1/speech:recognize. The behavior is unchanged.
sample_rate field has been renamed to
sample_rate_hertz. The behavior is unchanged.
EndpointerType enum has been renamed to
SpeechEventType enums have been removed.
has been renamed to
END_OF_SINGLE_UTTERANCE. The behavior is unchanged.
result_index field has been removed.
speech_context field has been replaced by the
speech_contexts field, which is a repeated field. However, you can specify,
at most, one speech context. The behavior is unchanged.
OGG_OPUS codecs have been
added to support audio encoder implementations for legacy applications.
We do not recommend using lossy codes, as they result in a lower-quality
speech transcription. If you must use a low-bitrate encoder,
OGG_OPUS is preferred.
You are no longer required to specify the encoding and sample rate for WAV or FLAC files. If omitted, Cloud Speech-to-Text automatically determines the encoding and sample rate for WAV or FLAC files based on the file header. If you specify an encoding or sample rate value that does not match the value in the file header, then Cloud Speech-to-Text will return an error. This change is backwards-compatible and will not invalidate any currently valid requests.
