Speechmatics is a cloud-based engine, which means network stability directly affects accuracy, latency, and overall performance. Even a fast connection can cause problems if it is unstable. This guide explains how to ensure a clean, reliable network connection for Speechmatics and other cloud-based workflows.

1. Stability Matters More Than Speed

Speechmatics does not require extremely high speeds. Instead, it needs:

• Consistent upload performance
• Low latency
• No packet loss
• No sudden drops or spikes

A 50 Mbps connection with stability is better than a 500 Mbps connection with drops.

2. Avoid Wi-Fi When Possible

Wi-Fi is convenient but can introduce:

• Interference from nearby networks
• Signal drops
• Latency spikes
• Reduced upload consistency

For best results, use a wired Ethernet connection.

3. If You Must Use Wi-Fi

Follow these steps to improve stability:

• Stay close to the router
• Avoid walls and metal objects
• Use the 5 GHz band instead of 2.4 GHz
• Disconnect unused devices from your network
• Restart your router weekly

These steps reduce interference and improve consistency.

4. Avoid Public or Shared Networks

Public networks often cause:

• High latency
• Packet loss
• Bandwidth throttling
• Unpredictable performance

Use a private, secured network whenever possible.

5. Check for Competing Network Activity

Other devices on your network can affect Speechmatics performance. Watch for:

• Streaming video
• Large downloads or uploads
• Cloud backup services
• Video calls
• Smart home devices updating

These can cause latency spikes and audio delays.

6. Router and Modem Best Practices

For maximum stability:

• Use a modern router (Wi-Fi 6 or newer)
• Update router firmware regularly
• Restart your router and modem weekly
• Use wired Ethernet when possible

Older routers often cause intermittent performance issues.
