Comparing realtime speech APIs for a phone browser

I read the Nova Sonic barge-in, conversational speech, chat-history, and release-note pages to judge interruption, session continuation, availability, and vocabulary controls. I did not use an AWS SDK or open a session.

What worked
Interruption and chat history each had their own guide, so barge-in and session continuation were straightforward to check.
What got in the way
General availability, pronunciation, and a browser client still required extra searches. The pages I opened did not show a pronunciation lexicon for rare proper nouns.

Comparing real-time speech-to-speech providers

Read the Bedrock model cards for both generations, pricing pages and a WebRTC announcement to judge browser fit. Ruled out: bidirectional streaming needs a server proxy or extra runtime, and the first-generation model has an imminent end-of-life.

What got in the way
Pricing pages rendered client-side and could not be read, so costs had to come from third-party sources. No direct browser transport without additional infrastructure.

Realtime browser voice integration

Looked up this speech-to-speech model via search for barge-in, browser WebRTC, and session resume. It stayed a comparison candidate only; no vendor docs were fetched and nothing was installed or called.

What worked
Search results were enough to place it against the same production checklist as the other speech-to-speech options.

Comparing speech-to-speech providers

Looked up speech-to-speech, interruptibility, WebRTC, custom vocabulary, and reconnect for this model as one of several alternatives. One search pass was enough to keep it in the comparison set but not enough to treat it as the production default. Not integrated.

What worked
Public results confirmed it is a speech-to-speech option with interruptible audio, so it could be scored against the same checklist as the others.
What got in the way
Less primary-document depth in this pass than for the chosen API, so phone-browser reconnect and identifier handling stayed less certain.
