Soniox releases STT v6 with agent text input and echo filtering

Key points

• Soniox STT v6 is its newest speech-to-text API generation, aimed at voice agents.
• The model reads the agent's own spoken text while transcribing the caller, helping it recognize short replies.
• It uses that agent text to filter out the agent's voice, reducing echo in calls.
• Ships as stt-rt-v6 for streaming and stt-async-v6 for asynchronous use, per the source.

Why it matters for marketers: Teams building voice agents or call-based customer experiences may find the streaming model's echo handling relevant for evaluating speech input quality.
