most of the Docker build logs
logs for gcloud sdk installation

This is a tracking bug, probably needs some breakdown.

• Need to write some queries to show case the index
• Add caching to the buildpack builds
• Add a CI build using buildpacks
• Consider adding more fields to the Cloud Spanner Table

Hi, I am trying to run the tests as given in the documentation here.
On step 9 it is given make run_tests I am getting some linking problem.

Hi there, I tried to use make run_tests under cpp-docs-samples/speech/api

but after a while this error shows up.

I wish to know whats going on, Thanks!!

Because we're always using the same Cloud Pub/Sub topic.

similar to this:
GoogleCloudPlatform/ios-docs-samples#7

i am experiencing the same issue
we are streaming AMR data at 8Khz, our buffer size is about 256 bytes per write request.
please help.

the session is able to transcribe the audio, but does yield the above message.

Hi,

I'm building an example (c++ based) in which I've a GRPC server which receives continuous audio 100 milli second chunks/bytes (using GRPC bidirectional streaming) from client (real time audio speaking from mic). My server code sends the audio to Google cloud speech to get text from speech. I'm using this example streaming_transcribe.cc. I've three questions:

1. How do I handle errors like: when I can not connect to google speech or can not create a channel due to network connectivity issues or server is down, how to catch such exceptions ? Also the stream errors out in the middle of streaming audio (google closes streaming due to time exceeds or long pauses), where and how can I handle such errors.

2. Client can keep sending audio for long duration ( may be like 1 hour). When the google speech stream is open for more than 5 mins, I'm getting the following error Exceeded maximum allowed stream duration of 305 seconds. The streamingrecognize requests have a limitation of 5 mins it seems as mentioned here. The same page mentions a few examples about endless streaming tutorials with some code in java and python. If I can get an example of how to implement this in c++ in https://github.com/GoogleCloudPlatform/cpp-samples/blob/master/speech/api/streaming_transcribe.cc, that would be very helpful, at least a peudo code.
   The examples mentioned in endless streaming tutorials closes current stream and reconnects new stream after about 290 seconds. But in the streaming_transcribe.cc, the stream is passed to a thread for writing audio bytes to the stream and the main thread reads responses from stream. How to close and create a new stream in the MicrophoneThreadMain (https://github.com/GoogleCloudPlatform/cpp-samples/blob/master/speech/api/streaming_transcribe.cc#L36) function ?
   A similar thread has been posted here but It was not that helpful for me.

3. How do we implement backoff and reconnect to Google stream (speech server) in case of errors (https://cloud.google.com/speech-to-text/sla). If I know how to catch or find the connection has errors (asked in [1], then we can implement this but it would be great to provide an example.

Any help is much appreciated , Thank you very much.

[Issue]
Running make run_tests fails when running asynchronous transcribe on audio.raw. The error message is shown below with steps to reproduce.

[Error]

[Steps to reproduce]

1. Copy this into a Dockerfile (https://gist.github.com/frankyn/07e01336391affc06929cb0e58a9fdb5)
2. Create a service account file and name is service-account.json where the Dockerfile is located.
3. Run docker build -t cpp-speech . where the Dockerfile is located.
4. Start bash docker run -it cpp-speech bash
5. In bash run cd /home/cpp-docs-samples/speech/api/
6. Run make run_tests

The example that connects and publish data to the core, its publishing data to:

/devices/mqtt-c-rsq2/events instead, it should be: /devices/{device-id}/events. It looks like its using the hardcoded value under opts.topic.

Hi,
I am working on ubuntu 14.04.

I've compiled the latest grpc(with libc-ares-dev (1.13.0)) and protobuf.

but when make run_tests:

ar: creating googleapis.ar
g++ transcribe.o parse_arguments.o googleapis.ar -L/usr/local/lib pkg-config --libs grpc++ grpc -Wl,--no-as-needed -lgrpc++_reflection -Wl,--as-needed -lprotobuf -lpthread -ldl -o transcribe
/usr/local/lib/libgrpc.so: undefined reference to `ares_set_servers_ports'
collect2: error: ld returned 1 exit status
make: *** [transcribe] Error 1

Seems like I've picked the wrong version for the c-ares, so how can I fix the error? Thanks.

Besides, the libc-ares-dev (1.11.0) will fail the make of grpc, so I manually make the 1.13.0 for grpc.

We have a number of Dockerfiles that could use some automation to keep them up to date.

I confirm possibility of building on Linux platform:
Linux Mint - yes.
openSuse - yes:
Ubunty - NO.

Is there any chance on Windows (MinGW or VS 2015) ?

Hi,
im trying to run the mqtt client example to demostrate publishing to google_cloud_iot. i followed the README file and installed all the dependent libraries, and was able to generate the executable also but while executing it, code it is throwing:

Thanks in advance!

This is working:

But this ain't:

The error I get:

Can someone tell me and help me why I can't create a function that does the initial configuration request? I'm using streaming_transcribe

The only thing that didn't work was the last two tests on GCS since the env variable wasn't set.
Can you use these instead?

Can someone help me with this?

Hi Jeff, I don't really have an issue per say but I used your sample as a starting point and I'm trying to add hint phrases to my application that mostly requires single word answers to voice prompts and the the API often returns unexpected responses maybe because of the Australian accent inputs.

To cut a long story short I thought phrase hints might be the solution but lacking any example code for c++ I cobbled the following together by looking at the auto generated header file cloud_speech.pb.h:

    RecognitionConfig *rc = streaming_config->mutable_config();
    rc->set_language_code("en");
    rc->set_sample_rate_hertz(8000);  // Default sample rate.
    rc->set_encoding(RecognitionConfig::LINEAR16);
    _**SpeechContext *speechContext = rc->add_speech_contexts();
    speechContext->add_phrases(std::string("hive,gown"));**_

I tested by saying <I've> (I have) and expected it to interpret as (my phrase hint) but it didn't. It returned <I've> which was correct(what I said) but I wanted it to take my hint instead. Is my understanding of hints wrong or am I not using the API correctly.

I hope you don't mind my request in this forum.

Regards,
Cal

hello. i'm beginner.

i'm trying to build this sample. but i can't build and run this sample.

i'm install gRPC, and protobuf, and i try build

7. Generate googleapis gRPC source code.

but filed to make, and I try use bezel build success.

but when i try 8. 9. i'm can't build

• cd cpp-docs-samples/speech/api
• make run_tests

error is log.severity.pb.h is not found.

• i'm usinb grpc 1.30.0

my question is..

now, this sample is can build? and run?

thank you.

Hey,
I'm using Google speech to text's v1p1beta1 library, which enabled me to send alternative language with a primary language. For one primary language it is working completely fine. But I'm not able to figure out how to send multiple alternative language ? Google's documentation states that upto 3 alternative languages can be sent.

Looking at cpp-docs-samples/iot/mqtt-ciotc/ the example is not able to run on an Arduino device.
I would like to ask for the support of the Arduino environment to be supported, this would allow as vast range of arduino IOT to use Google Clould IOT service, including the MQTT service.

• Dockerfile: Add some more comments so the Dockerfile can be more easily followed by someone new to containers.
• App Code: "World" should be overridable with the environment variable TARGET.
• README: 1. No need for beta component, 2. Unless using Cloud Run for Anthos, no need for kubectl

Pulling the repo fresh and following the instructions in the readme results in this failure:

When running "make run_tests" the very last check "./transcribe -b 16000 resources/audio.raw" fails with message "Sending protected frame to ssl failed with -1".

I understand this is an issue with grpc, but I am also able to run client server helloworld there just fine (I'm talking about this: https://github.com/grpc/grpc/tree/master/examples/cpp/helloworld).

Any idea what could be causing this?

Hello all,

I am trying to use Google cloud Speech for speech-to-text using streaming API. The samples work for me fine, however my usecase is a bit different: I would like to do continuous, streaming speech recognition (multiple requests). So I face two issues:

1. It looks like I cannot use grpc::ClientReaderWriter<StreamingRecognizeRequest, StreamingRecognizeResponse> for multiple requests because I get an exception: assertion failed: call_ == nullptr client_context.cc. So, I have to recreate complete config (credentials, channel, context, config request) for each request and I don't find it elegant because it adds unnecessary overhead.

2. To avoid any latency due to the config creation I create it beforehand and wait for the audio samples from mics. However, if the audio samples arrive a bit late I get Audio Timeout Error: Long duration elapsed without audio. Audio should be sent close to real time.

So my question(s): What is the correct way to use google streaming API in C++ for multiple requests: Due we have to renew objects for each recognition requests and Is there any way to avoid timeout?

I am working on Ubuntu 14.04 LTS. The speech API code was downloaded in April 2018.

Thanks.

What does this line of code exactly do ?
SPEECH_PROTO_PATH = google/cloud/speech/v1beta1

Here is the error I'm getting:

According to google the Google Cloud Speech API is now Generally Available.
Within this change, some other changes were made on the api.
Does it influences this demo program? What kind of changes are needed to migrate this demo to the new GCSAPI version?

Now #57 will add 2 builds, presubmit and continuous. We probably should have more builds.

We use CPP Google Speech APIs to transfer voice into text, it works fine for English, but not good at split sentence for Chinese. At result, we can also received the last sentence text, didn't be cleared when new sentence start, not same as English.
Is there are any APIs to solve this issue ?

Our codes are:
void Run()
