We are happy to announce Realtime-API SDK 3.9.0.

Upgrading is straightforward with our release process, which adheres to Semantic Versioning. Minor versions are guaranteed to not have breaking changes, so you can upgrade with confidence.

SignalWire Release Card

Version 3.9 of the RELAY Realtime SDK includes a couple of improvements for Voice calls.

Highlights​

Enhanced Speech Recognition​

Enhanced speech recognition is now available for speech collection. Prompt and Collect methods use a speech configuration object to specify how to collect speech. The new optional key model enables enhanced speech recognition at an added cost with any of three possible values: enhanced, enhanced.phone_call, or enhanced.video. phone_call optimizes speech recognition for phone calls at an 8khz sample rate. video optimizes speech recognition for video calls at a 16khz sample rate. The value enhanced will automatically detect whether to optimize with the phone call or video setting. 4e8e5b0d

const collect = await call.collect({
  speech: {
    endSilenceTimeout: 1,
    speechTimeout: 60,
    model: "enhanced",
    hints: ["one", "two", "three", "four", "five"]
  },
});
const result = await collect.ended();

See our Voice pricing page for pricing information on advanced features.

Set a Maximum Price per Minute​

The parameter maxPricePerMinute has been added to call.dial and call.connect methods to allow users to set a maximum price limit for a call to be created. If the rate for the call is greater than this value, the call will not be created. aa31e1a0

try {
  const call = await client.dialPhone({
    from: "+YYYYYYYYYY",
    to: "+XXXXXXXXXX",
    timeout: 30,
    maxPricePerMinute: 0.0075,
  });
} catch (e) {
  console.log("Call not completed.");
}

The cost of a call can vary by rate center and call features. In the example above, if the call charge is greater than $0.0075, the call is not created, and a 30010 error will be returned with the message, "MaxPricePerMinute was exceeded. This call's cost is XX."
